I very much doubt anyone has become a billionaire threwthrough gambling
There is no doubt that there are some people that are rich through "gambling". It need some skill and "luck" which most people dont have. The winner of the WSOP will receive millions of USD which serve as a fact that some people are rich through "gambling". PrimeDice 100 BTC leaderboard would serve as another fact that someone could be "rich" from gambling and thats of course is just a niche of the whole example
The most lucky man, Hufflepuff is the example although and it end he was being accuse for cheated but at least he can successfully withdraw his huge winnings and he was spend his quality time for fun.
I'm wonder he will back again for try another luck but usually when people want to try another luck, mostly will busted
