That depends on the situation in the country. If culture, religion, and the will to make money from gambling are high, they will gamble. But gambling addiction problems may happen in that country even if that is a small percentage.

Let's assume that a country has a better economy but its people can not realize the effects of gambling, they will still gamble and maybe many people will become addicted. They will deeper into gambling and face the gambling addiction problem.

Maybe we see the US people gamble more than others but we never know how they can prevent gambling addiction. Maybe that existed but we never heard about it. We may hear many people become addicted to gambling in poor or developing countries.
