You can't avoid having kids playing with money involve, Because even the parents give them money to spend, their young minds tend to think at first they will buy food or toys and when it is not enough they will try to bet their money in playing games just to have more, Of course it is inevitable for them not to try it because there are so many influences you see in the real life and by watching Television.
moral of the story you will teach your kid good manners and teach him to buy CUPCAKES and SNACKS rather than BETTING. My doubt is how would your kid know about gambling unless and until he sees you gambling and that makes you a bad parents 
OP being a kid made a thread and disappeared
