As a parent, I think everyone does that, but it can't be done forever because they will also know it themselves from the outside environment or from their friends.
I myself see that in my environment, parents don't gamble much, maybe it can be said that only a small number of parents gamble. However, when looking at the age of teenagers, almost all of them gamble. So is this because they see their parents gambling? Of course not, but they know gambling from the outside environment or from friends who already know gambling.
If you are a parent who truly cares about your child's daily life and future, you will always have a way to help your child stay away from social evils or things that are not age-appropriate. Because it is our responsibility and duty as parents, not anyone else's. If our children unfortunately get to know gambling and become addicted to it, don't blame the environment or the development of technology, it's our fault. Because we have not been strict in teaching and managing our children.
I don't know if you have a family and children but for me, with the development of technology and always arranging time to take care of my family life. I hardly have too much difficulty in teaching and managing my child, I do not find things as difficult as many people complain.
