Can you be sure that they were in a lower vibration of lack? Maybe their surruondings were but mentally they were in a high vibration thus thier winning just the belief and the buying of the lotto ticket can be a possitive step toward the vibration of winning.
A person can have abundance and not have wealth.
A wealthy person can lack more than the poorest street beggar. Try not to judge things as they appear observe and understand.
If one likes the word "luck" and believes in the word, then the word as the power of the persons beliefs and faith, and or lack there of...

• Edit : I was cleaning up my in-box and found this from the daily quotes I receive

We want you to understand that abundance expands proportionately to match desire, and that there is great untapped abundance not yet allowed by the very humans who have created it. When your life experience causes a focused desire within you, the means to fulfill that desire is created at the same time—but you have to be on the Vibrational wavelength with your desire in order to see the path to the fulfillment of it.

A belief in shortage or lack will prevent your discovery of the path to your own creation, and any feeling of resistance indicates that you are on the wrong Vibrational path. However, in your understanding of the never-ending abundance of this Universe, you will feel personal delight whenever you observe anyone’s alignment with it, for their achievement can in no way diminish yours, but can only enhance it.

As you focus upon your breathing and the music and words of your meditation recording, you will deactivate your usual resistance to abundance, and you will discover the satisfying feeling of positive expectation and success. And then, the manifestation of that success must come to you. It is Law!

Hi Cory...my guess is that these people have had enough of living in dirt poor surroudings and to escape they start imagining that they are living a life of luxury...the fact that they know nothing of the law of attraction can be an advantage...they don't know it exists so they don't put up any mental barriers of doubt...the law of attraction is always at work whether we realize or not...so the exact conditions for manifestations are fulfilled.

Now that i think about it, i remember that in my youth i often experienced this kind of phenomena...at the time i thought nothing of it...it is after all a natural phenomena.

Im sure some poor people obviously build up a very strong desire to be wealthy because of the contrast they are living. I have heard Abraham say that a very strong desire can sometimes override the belief system and this person can still manifest what they want.

However because they are not a complete vibrational match to it they cannot keep it in their experience. This ties in with the stories you sometimes hear about how some lottery winners lose their wealth quite quickly again.

Bashar was once asked, "How do I win the lottery?" He says that the way you do that is by shifting your reality into that reality which matches your numbers. Then he goes on to say that what most people are doing when they play the lottery is exploring their relationship with material wealth, and it's in that exploration that most people win, not in actually getting the money.

He also points out that, while most people want to win the lottery, they are not as passionate about it as they are about the things they think they will get if they win the lottery, and that there are probably better (and, I daresay, more likely) ways to achieve the things that you are truly passionate about.

Bashar on playing the lottery

I cannot add much to the already excellent answers that have already been given. However, here is a current reminder (from today's news) that the vibration of abundance does not necessarily have to manifest by way of a lotto win, or even via cash, check, or money order:

A California couple on their daily walk with their dog, a walk they've taken for years, discovered what may be the greatest buried treasures ever found in the U.S. The cache of rare Gold Rush-era coins is worth more than $10 million, a currency firm representing the pair said on Tuesday...The couple, identified only as John and Mary, had been walking their dog when they came across a rusty metal can sticking out of the ground and dug it out. The rare and perfectly preserved U.S. gold coins date from 1847 to 1894 and have a face value of more than $28,000. They could sell for more than $10 million.

Some more interesting details:

"It was like finding a wonderful hot potato," Mary added. "I never would have thought we would have found something like this; however, in a weird way I feel like I have been preparing my whole life for it." The couple said they plan to keep some of the coins and sell others with the intention of donating part of the proceeds to charity. More importantly, they said, they will use the money to hold on to their home. They did not explain further. "Whatever answers you seek, they might be right at home," Mary said. "The answer to our difficulties was right there under our feet for years."

From an interview with "John" and "Mary":

Q. Why do you think you were the lucky ones to find this treasure? Do you believe it was divine intervention or karma?

Mary: I never would have thought we would have found something like this; however, in a weird way I feel like I have been preparing my whole life for it.

Q: How?

Mary: John just knew what to do - it was a little bit karmic... Perhaps in some way we were the ones that could honor the coins.

Q. You have an interest in astrology; have you checked how the planets were aligned or what your chart said at the time of discovery?

Mary: Actually, I did look back at it. It's very funny, my chart did talk about treasure, but it was more about the treasure of spirit....

Q. Would you say that your "dreams" have come true?

John: Like a lot of people lately, we've had some financial trials. I feel extreme gratitude that we can keep our beloved property.

Q. Estimates put the value of this find at over $10 million; better than some lotteries. What will you do with all this money?

Mary: We love our lives as they are - I hope we can help our family members and our community and give back some.

Q. Are you going to quit your jobs?

John: No - we're self-employed - the beautiful thing about self-employment is that you can go to your grave self employed.

Q. You have chosen to remain anonymous out of concern for your family's safety and potentially from being overwhelmed by the media. But how do you think this find will change your lives?

Mary: We're the same people we were before, just with more freedom of choice. Our finances won't have to dictate so many of our day to day decisions.

Q. Some lottery winners have later said that such sudden wealth ended up being more of a curse than a blessing. Have the two of you discussed how you will navigate the path ahead and the potential pitfalls that might come with instant great wealth?

Mary: We try not to dwell on the negative.

John: It will be a broader path than the one we have been on.

Mary: Money can change other people's perception of us more than our own perception of ourselves. Have you heard the song by Cindy Lauper, Money Changes Everything? We don't want that; we don't plan to tell our extended family or friends until more time goes by.

Life is bigger and more mysterious than the teachings of Abraham. Many people who get what they want say they never expected it. Not everything is created by conscious thought alone.
