A teenager will need to get money somewhere to constantly gamble, and I’m actually not against the fact that if there is a lot of interest, the teenager tries to play, so that he understands that it is very easy to lose money in gambling, perhaps this experience will be enough for him to understand that everything here is not as simple as it seems, that in addition to luck you need to have many other skills, without which there is nothing to do here. I doubt that from playing several times he will get some kind of addiction, but I believe that he will be able to understand that it is not for nothing that this activity is prohibited until adulthood.
If there are many good things that a teenager must learn about while growing up, learning how to save money, how to invest, and how to manage their financial lifestyle in order to grow their wealth is a very important aspect they need to learn. Gambling at a tender age can make them bad players in the area of financial management. Although some of them can still be cautioned by their parents, but some kids can really grow up to become addicted gamblers and face a difficult lifestyle because of their bad habits of gambling. I have witnessed a friend of mine in college who was really so addicted that he spends every money he gets on gambling.
Anything that leads to something that can be useful for life will always be something that is recommended for anyone to do, as you said, managing money, saving or investing is a good plan that should be prioritized, especially by teenagers who Of course, this will be useful for supporting their lives in the future when they are no longer dependent on their family, or that is, when they are free from their parents' responsibilities.
On the other hand, we can judge how gambling is, overall, as we can see, the bad impacts are more prominent than the benefits, meaning that gambling is included in the group of negative activities that should not be done, especially by a child who is still in the teenage stage, which is usually it is a situation of change in maturity and it is also a situation for determining future goals, and what is more dangerous is when their personality has been completely influenced by gambling, because it is clear as we know that gambling can change good people into bad people in a short time especially when they gamble in the wrong way which can certainly threaten their future.
I am sure that all parents always want the best for their children, but sometimes not all parents are able to educate and direct a child properly, and usually parents are negligent in supervising them so that in the end it is very possible for them to end up in a bad environment. Of course, it has the potential to bring about various bad possibilities that can change their personality, so in fact if we make a child who is still a minor an object who will become a victim then of course everything depends on how the parents are able to supervise, direct and educate them.
