No one becomes rich from gambling. You can observe better people around you if someone had ever won that just lost money again back by keep playing. Gambling let you win but bring you back in game to try to make much more and you loose all. You can win but can't keep that money for longer time. That's why can't become rich from gambling.
That's correct, some gamblers just won their recycled money... But some fellas are also lucky that they win big in their first try, and sometimes they hit it betting big amount, too bad that some of them are not wise enough, they still use those winnings to gamble and thinking that they will win larger than what was in their hands...
Gambling not and never make to rich, it's hard to get it in gambling, maybe any one get rich from gambling but he's a professional gambler and have a lot money to playing. But money from gambling is very easy to lost again.
If you have big capital, sometimes you would think that you are really winning, but if you compute every busted bets that you've made, I think you would still think that what you won is not enough...
