I am a day old in this forum and am understanding some ways in which one can get rewarded and one of such is gambling, but again, one needs to understand the risk involved.
As the others already said gambling isn't a way for you to get rewarded if you insist treat gambling with such a mindset or treat it as a source of income (in the worst case) I believe sooner or later it would suffer your life. Gambling isn't the way to making money instead of one of the ways to entertain ourselves from our routines, in case you are planning to build up your own wealth it would be wise to avoid gambling as much as possible.
