There are some people that made enough money through gambling but that is a real rich because it is not guaranteed to stand forever because you are not going to earn every month or weeks but it is once and when the money has been exhausted then you became poor again. So gambling millionaires are just for the main time and not for ever lasting. Gambling can make someone to become a millionaire for a short time.
The individual determines whether or not to remain wealthy after winning a large sum of money in gambling. Of course, you do not win millions of dollars every day or every week as you mentioned; most of the time, it is just once in a lifetime, but some people will use the money to find a way to be financially stable indefinitely. Their investments may not be in the millions, but they can always expect a profit.
Without a doubt, some people will become even more frustrated in life after winning a large sum of money because they are unable to make good use of it. Some gamblers in this category will increase their stake and continue to gamble in the hopes of repeating their luck. Others may begin to live lavishly without investing, and the money they believe they have will soon vanish, leaving them with regrets.
Personally, I believe that winning millions is not the ultimate goal, but rather a gambler's ability to make good use of the money won. However, I believe that every gambler, regardless of how he intends to use his winnings, should be fortunate enough to win a large sum of money.
