In the past where I think gambling can give me good money for my future, it did not, it brought the other side to me. Success can be found on gambling but there are just a handful of people that can do that except the casino and gambling site owners obviously. Gambling is a game of luck, if you are not lucky then you must not gamble, I do not know if there are people that are lucky either.
Or if you are not lucky, you gamble more. This is just how probability based gambling works. It all about randomly trying multiple times until you hit the right one
