Even if you give so big details,the gambler will always play gambling until he is not finish his bankroll. So in simple words everyone know about it even then they gamble
Right mate gamblers already had the idea what will be the outcome if ever they will be addicted in gambling but still they play and trying their luck but sadly most of gamblers never success and got broke.
The problem is that mindset that even though the chances of losing is huge, the possibility that they can win big is also there and when the choices come staring at them, out of greed and the impulses that comes with gambling they tend to stick with the idea that as long as they keep trying, maybe that one more chance can actually give them that big win until they keep doing that and they end up losing it all. That is the problem a lot of greedy and unreasonable gamblers face.
