No no, gambling is not a destructive entertainment because it is the same entertainment in general, it's just that it is said to be destructive because of excessive behavior in doing it, such as those who do it too much, such as depositing money back into gambling when they have lost, now if gambling is done properly there will be no problems. I think it's more about them having to have a good understanding of gambling so they don't get addicted to gambling, because when you are addicted to gambling, it will be difficult to get out of that zone.
Many different entertainments require spending money, but this does not mean that they can cause us addiction, or that there is something wrong with them. Everything will depend on how we treat them. If I can control myself in gambling, then I can use my bankroll wisely over a long period of time and will not spend it quickly on a few bets, but will distribute it over many bets. That is, gambling cannot be a scam, unless it will be as a perception of a player who wants to shift his responsibility to others.
