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.
It has psychological problems as we know that some gamblers get addicted of gambling and can not live without it but it is a disadvantage besides which it has many advantage. If someone starts it for fun and entertainment then it is always here to entertain you. Gamblers play because they believe that one side will win and one side will lose so they see their chances of winning a game.
I have seen many gamblers committing suicides due to debts in gambling. They are not able to recover their debts and they want to escape and suicide is the easiest way for them. Most of the gamblers are also criminals and they do every illegal activity to make some money for gambling. They have no respect in society and even in their families and relatives.
