this analogy might be too much, because i also grew up in an environment where people gambled every day, but i didn't grow up being a gambling addict. because it still comes back to the individual, because many gambling addicts are born from good families. so even though it is not recommended to gamble in front of children, even if we gamble in front of them there is no certainty that they will gamble more than we do.
Also true, it's on the person itself whether to take part in gambling or change his way but the influence it can bring can't be deny which if the kids see things as normal usually they will follow that track, thinking that its' just normal since they are seeing adult people that surrounds them are just doing it without any conviction.
This how important your cares about your kids or on the young minds that still in your vicinities, they can be influence if you are not careful with how you treat your gambling.
Adults will usually be used as an example by young children in any case whether it is from speech, treatment, and something done by adults, a child will not know something that is done by adults is basically forbidden, and this is why the job of parents is to teach and direct them to good and right things and keep them away from something bad of any kind. This means that I don't think it depends on whether the child wants to follow something that is done by adults or not, because the main point is that when they see that adults are doing it openly then they will most likely think that it is something that is allowed to do, and this is why we as adults are advised to hide gambling activities, none other than because after all prevention is always better than cure.
On the other hand, children usually have a high level of curiosity about anything they see, especially those that make them curious and interested and it is possible that the excitement reaction that you experience when gambling, especially when you win, can make them interested and curious, and of course as you said that we must prioritize care, this concerns the safety of the personality of a child who still has a long future.
