Yes, in my opinion there is a good side and a bad side, in some countries gambling are prohibited and the user can even be arrested, on the other hand gambling can help the country's economy to develop and attract tourists, for example Las Vegas
There's always a bad side of things if used excessively even food can be bad too but there are lots of people who take everything excessively especially those things that have given them bad results. If you play more than you have then that will fell into addiction and when you think of it every day, then that falls into addiction too. This is where most people fall into, they cannot control their desire, and most of the time they affected some people with that kind of mindset too. Those countries are top to those kinds of people.
