Someone just argued with me that gambling can be done by kid too..

Yes! you can say that if the kid is gifted with knowledge on gambling or he has much luck on his side but then again if you're a veteran at gambling games then you will be top of that kid that is gifted if not its experiencing the gambling game a kid has not yet developed some of his adult hood so if he really knows having a adult mind his that will happened the kid will gambling games and its really bad if kids play gambling because they will ruin their lives and can't smell the free world of a kid playing video games and such a kid is not suitable for gambling it will ruin his future or her only adults will play gambling games
