So for at least I never heard anyone become a wealthy from this hobby. Everyone want a fast money and without doing any hard work and that's why so many gambling sites are popping up to make profits for them but gamblers always at the losing side. These guys know that they can't win, but still, they will try their luck until they lose all of their money. We should gamble only if we need some entertainment but shouldn't go to gamble if you need some money.
Also, people that become rich from different fields usually go talk about how they've become successful. Most of them can't even stop talking about it. But as a gambler, there's no point in talking about how he got successful unless he has some good story behind that.
