Each person has his own understanding of this world, so not all children accept the instructions and advice of their parents. No matter how much you teach such children, they will act only according to their own interests without listening to anyone. Such children have always been and will always be. And this applies not only to the attitude to gambling. Therefore, I think it is very important not to gamble in front of children, because we can not predict their attitude to gambling, risks and understanding of this sphere of entertainment, and therefore to protect them in case of problems.
Ive read some advice or quotes that say that parents are the best teachers for children and that is indeed true .
Young children always make their parents as role models in the sense that here all forms of words and actions of parents/closest people will influence the child's behavior.
Indeed in this case when everyone has entered adulthood and can be responsible for what they do it will not be a problem to gamble or maybe they have a greater interest in gambling even though its not an obstacle because they are adults, can earn money independently and are able to be responsible for what they do. But that does not mean that in this case we have to show activities like this to children because even though our reason is to say that this is a form of learning in fact it is a mistake because it is precisely actions like that that can change a child's mindset, especially if the child is still small (young age) .
