This shows that you dont have kids, or dont pay much attention what they do during free time. You see the situation from adults point of view, but kids (I mean like real kids, not teenagers) dont care much about money. They have parents to solve all that "money moments". So when the kids see money on the table, first they get excited if there is a lot, but often quickly lose interest to it. You know, the kids rarely measure things different than adults. They rarely use "money" to measure things. When they see something, it is big, small, shiny, tasty, red, heavy and etc. They dont measure things as "that cost 9.99", "this is 100 bucks", "wow that cost like 3 my monthly salaries", "this car cost a million".
Regards your phrase that I have bolded. When I was a kid I bet 3 chewing gums that I can swim the pool faster than my friend. From your point of view, I with this bet I did something bad and I did not deserve to even place that bet. But, I believe, when you was a kid, you did similar bets either.
At least the children in my neighborhood don't gamble in their free time, and I see them playing like children playing with their friends. Likewise, if I ask my neighbors who have children, they also don't see anything hidden by their children. The parents around where I live really know and pay attention to what their children are doing because the relationships in my neighborhood are very close. So the children don't do anything that violates the rules, so the parents don't need to worry about it. Older children also help supervise younger children and keep them from doing anything that might be bad for them.

I did something like that when I was little, but that was in the past, and I didn't teach my children to do it. It's enough for us to experience it. We must take good care of our children. After all, if they don't know gambling, that's okay and better for them.
You did not say anything 1)why gambling is bad and you think it is better not to show them it 2)why kid will become gambling addicted if he sees that adult gamble?
About my example with swimming and chewing gum. It was all done to make competition more interesting, to increase desire to win. Why do you think it is bad to do that? In this case, a bet = a reward.
