Of course, and sometimes we don't realize that it turns out that the child can already do something that we never expected before or for example in terms of speech, sometimes we don't know about when they learned it and how they learned it and all of that they did on their own without our knowledge or especially the parents and I also saw this scenario where my brother was surprised when he saw his son apparently saying harsh language that should be avoided. This does not rule out the possibility that this scenario can also occur in gambling, or the point is that a child can participate in gambling activities carried out by adults without the knowledge of these adults.
True, we never know or we can't really tell if how those young kids going to adopt whatever they are seeing or hearing from us, most of the times we are just being surprise that they already saying it or doing it, we will just notice that when we already witnessing it with our own eyes, so we need to be more careful if we don't want to expereinced things like that.
On the other hand, I understand that this does not always happen or mean that it cannot be confirmed, but what we must pay attention to here is that isn't prevention always better than cure? of course, therefore this is the importance of considering and paying attention to whatever is around us before we finally make a decision, and someone who is still underage is an age where the child is in the learning phase or meaning that they are like a sponge, always able to absorb whatever they see and hear, this is why parents are always required to direct a child.
Prevention also for me is the best way, treating things with a careful actions will prevent our young love ones to adopt whatever gambling that we are involve, if we are not willing to see them engaging with that same situation like us, we should always be aware on how or what things that we will show them and what are those that we should not.
