It's not a matter of pride or not, in the environment where I live it's exactly like you said, if they know there are gamblers they will think we are very bad, and in my country gambling is strictly prohibited in all ages so it's normal they can think like that , but if fellow gamblers it doesn't matter if they know that we are gamblers, so I better hide it, for convenience
In Southeast Asian countries, there are many people who believe that gambling is a bad thing. But don't we realize that there are now many online gambling game platforms with virtual cash, which has become a subtle campaign so that people start to want to know about real gambling. Even in certain countries they don't ban these applications because they don't use real money but virtual money. Like it or not, almost everyone is now forced to gamble, whether for reasons of mere curiosity or even to the point of actually getting involved in real gambling. So I think hiding that we are actually gamblers is impossible nowadays, in fact there are many young people who show off on social media about their gambling activities.
