People are allowed to have a gambling business in my country and citizens are allowed to play so far the person is already 18 years of age or more. Underground gambling are illegal gambling but if gambling is legalized in a country, people will prefer to get registered instead and make their gambling sites legal. This is better than trying not to pay tax but in a way the gambling site can be known and shut down by the government.

I have many gambling platforms that I can use legally, then why underground gambling? As for the online illegal gambling sites, they are not located in my country and I avoid them because I do not trust them. I okay on foreign sites like Stake, but they is because they are not illegal but legal.
