well. you have a point, maybe being a lowkey just to protect a gamblers from some evil eyes that may surrounds them, we all know that some people doesn't agree and support you once they know that you're into gambling and There's a traditional belief that once they know what you're doing, they can ruin it. In a gamblers vocabulary, Luck is very important that's why sometimes they tend to hide what they are doing even in their family members just to avoid losing in a game. Having a self control and limitations is a must and if gambler feels that they are turning being addicted to it, maybe that's the time that you can tell it to them.
If it's related to traditional beliefs, we can't relate to anything because they will easily judge gamblers by giving bad opinions, so maybe that's why there are still many gamblers who hide their gambling activities from other people because they don't want to get these bad opinions. They tend to choose to keep their gambling activities hidden from other people, even their own family members because they feel more comfortable doing so. They will also not experience a lack of self-confidence when hanging out with their friends because they are completely unaware of their gambling activities. Indeed, when they choose to hide their gambling activities, they must have better self-control so they don't experience any problems while gambling.
It can be difficult for a family to prevent a gambler from exceeding their limits, even if they are aware of their gambling habits. It is up to the gambler themselves to take responsibility and make a conscious effort to prevent it. The family can support and encourage the gambler, but they cannot force them to change their behavior.
Yes, that's true. His family won't know what the problem is until a family member goes beyond his limits in gambling and becomes addicted to gambling because he has hidden his gambling activities from his family. This requires awareness for him to admit to his family that he has a gambling problem and needs help from his family. However, a gambling addict may still hide his gambling activities from his family and think he is still fine. But if he is willing to admit his gambling addiction in front of his family and ask for help, he might be able to get help from his family soon so he can overcome his problem.
