is gambling made for kids? NO. but can kids gamble or know how to? DEFINITELY.
kids know how to gamble, too but not on casinos of course. take POGS for example. it's played by having as much as possible POGS in a round and the one who have the most is the considered winner. Some schools even banned it because kids keep the Pogs they won from other players.
kids doesn't understanding the concept of gambling but they do know the concept of winning. you win in something, you get things.
Kids just gamble to have fun and maybe take the money if given the chance but that is not good for them since they are still in the stage that they have a limited understanding in life and since gambling is a very risky game, it should be played only by those people who are matured already and know how to manage the risk in gambling.
