I'm not rich from gambling but you can become rich by gambling with a lot of luck of course. I think if you have this luck you should never gamble anymore because you can only lose it again in my eyes..
Even with luck you cannot become rich with the gambling because yes with luck you may win a huge amount one day but in contunuing gambling its 100% sure that you will loose again while doing gambling or even more than that,anyhow its not possible to be rich with gambling.
Always aim for the jackpot so you will not gamble regularly, when you are lucky regardless of the odds, you will still win.
