This teenager still needs guidance from his parents, especially since he is new to new things. If his parents can continue to accompany him by providing sufficient advice and knowledge, he can look after himself, especially when socializing or hanging out with his friends.
The role of parents is very important for their children who start gambling, because basically gambling will not always give them a win let alone make it a source of income, I think it is necessary to guide them slowly, it could be that the child has become an addict but is still within the limits of his control. not aware, usually just addicts will not want to listen to anyone.
If he is not an addict, he should listen to what his parents say for his own good, especially since he is still underage and doesn't have enough time to gamble, at least continue to high school such as college to become a successful person, not become a gambler whose future is very bleak for the most part, so to Guiding this child must be done slowly and at the same time explaining the risks and dangers and not pressuring him to stop gambling quickly because this requires a process of changing habits.
If parents find out that their child has started gambling, they must provide more understanding and a different approach. Their children must be guided to stop gambling before it is too late and their parents cannot save their lives.
Even though their child can control himself, his parents still have to explain and guide him so he can stop gambling. Parents who really love their children don't want to see their children involved in gambling more deeply. And before that happens, they must immediately get him out of gambling.
With the approach parents take, they can slowly make their children aware that what they do is not good for their mental health. The presence of his parents in guiding him out of gambling can help him to leave gambling and never gamble again.
