I am sure that they will get angry with me if we play gambling together because my father doesn't like to see their kids playing gambling games. Usually, I gamble in my room without anyone knows, and if my parents get into my room, I will close the gambling site right away before they see me playing gambling
Besides introducing about gambling to their kids, maybe parents need to tell their kids that gambling can suck their money until it's run out. But I think it's not better to introduce gambling to the kids before they are growing up so they can think about the risk of playing gambling. I am sure that they can think about the positive and negative of gambling and they will choose to not playing gambling as often.
