One thing we need to keep in mind is that the children of today will determine the future of tomorrow. So we as Guardians cannot do anything that endangers our future generations. As guardians we must try to fulfill all the responsibilities we have. Unnecessarily they cannot do any criminal or prohibited activities in front of them. When family members participate in gambling in front of a child, they tend to focus on those forbidden activities and show self-control. If a child sees family members, it will definitely matter and will become a gambler unconsciously. Therefore, as much as possible, we should avoid gambling, drug addicts, violence, and other social crimes in front of children.
What a candid and articulated submission you've got there. I've said it on this thread before now that it's the responsibility of every adults to make sure kids are protected from consuming any sort of content that's exclusively made for adults because failure to do that is an easy way to endanger the lives of such kids.
For parents, it's advisable that you make sure you don't engage in any kind of activity that's detrimental the future of your kids of which gambling halo to be one of them.
