Becoming rich from gambling is really hard first thing is it's really hard to get luck when playing gambling yes playing gambling is just simply thing to do but it always based on the odds and your bet if your bet's is really high then you will lose or either win high also some people are making good profit in gambling.
I think yes it is hard if you are always at play. But once you strike your luck in gambling and stop I think it is a good idea . But if always play, it is hard to maintain your wealth. Also if you are in gamblig, other vices may comes in like womanizing, drinking intoxicating alcoholic drinks etc.
But when we are going with big bet amount then we must stop gambling right after having some profits otherwise we could not save our bankroll in short run itself.
