I agree with you, it is better to stay as far away from an illegal casino as possible, look, gambling is completely illegal in my country, and because gambling is illegal in our country, there are no physical casinos, even if there are physical casinos running their business secretly, they are caught by the police very quickly. in general, I see that physical casinos are strictly prohibited, not only physical casinos but also online and all types of gambling are prohibited in our country, but gambling is very common in our country, all gamblers gamble only in online casinos, and everyone is secret in their own way. However, in countries where physical casinos are legal, you should only go to only that legal casinos, it is better to gamble in online casinos than to go to illegal casinos.
Without being precise about what the business men and politicians do behind the gaming room, it's assumable that they also create games that the general gambling community won't be aware of, and only a few selected dignitaries could be allowed access. They'll make too much money and yet remain secret and untraced for years.
