Gambling habits doesn't really pass from the gene of parents to children, most children are easily influenced by the hobbies of their parents. Normally most male just have interest in gambling because of the money it brings .
The question is whether parents want their child is involved in gambling or do excessive gambling? I think that gambling is such a game that even though parents play it themselves, they do not want their children to inherit this habit. However, if you play openly then children will watch you gamble and they will develop an interest in this. If you want that your children do not inherit this gambling habit, you should not gamble in front of your children.
I think parents don't want their children to be involved in gambling, let alone inherit it. This is really ironic if there is something like that, but what I experienced I never showed my gambling game in front of the children because they can't know I'm afraid they will be involved later and become addicted.
My gambling game has never been opened by anyone, let them know for themselves when they grow up, but if they are still children, of course it is still under the supervision of their parents, I emphasize that I do not want to inherit it. It is too risky if I tell my children how my gambling journey was.
