When will you stop using kids and gambling in one sentence? They arent so big gamblers and interested in gambling as you think. And even if they gamble, as soon as they run out of money, they stop gambling and feel sorry for wasted money. They are not like adults, who find a way to get new money after they lost. Check what kids are doing, looks their browsers history, monitor how they spend free time and you would barely find something gambling related there.
Man, do not generalize, be happy that you are around kids who are not interested in gambling, or haven't had bad friends who introduced them to the world of gambling..
I myself have lived in a ghetto area, filled with gangsters and wayward lifestyle was like the norm over there, children born into families who live in such places end up as addicted gamblers even as young as 12, 13 years old, in such places, children gamble with other children while adult gamble with other adult, and you know what? Online gambling is not a thing for them over there, so, there is really no phone Browsers to check it's history, and how do this children raise money to play gambling with? Nothing else but stealing, both from parents and people out there, and some do manial jobs, they use their school handouts, some even gamble with their school fees, some sell some of the stuffs their parents bought for them and so on.
