And you did the right thing. Society definitely condemns gambling, and I think it condemns it too much. Yes, there are plenty of examples of problem gambling and betting, but I also know people who have been gambling for years and do not suffer from addiction. However, children are the factor that any reasonable person would immediately exclude the risk that gambling brings from their life. And I would do the same.
On the other hand, you have mentioned that there are some gamblers who have been involved for decades but they have never been addicted and indirectly that is one example that as I said above, what is bad is the behavior of gamblers and not gambling itself, in the sense that if you are able to treat gambling according to your abilities then you will not experience many setbacks in life as a result of gambling, and this is the reason why self-control and various limitations are always recommended to be applied.
