If I become a parent, of course I will not let my child get to know gambling or others first before earning their own money, I will not show that I also play gambling in front of my child or even I allow it with reasonableness in the future in the child's growth period.
That's a good one and make sure that you're going to do that to your kid. Do not show any sign that you're a gambler in front of them.
These kids idolizes their parents and that is why only show them what's right but let them do what they want when they're on the right age to do what's necessary and their stuff.
In the case of kids, I would never encourage them to earn money because if they rush towards money income at an early age, they will be held back by the natural growth that comes with age. Young children think of their parents as their greatest teachers. Whatever good and bad parents do in front of children, children try to imitate it attentively. At that time if a parent shares the gambling related matter in front of the children then they will surely imitate it and at some point they may be encouraged to gamble. So parents must be careful about these things in front of children.
