I'm not sure about this statistic. It seems to me that there should be other countries. I read a study that more gambling is done in poor countries. This has to do with the fact that people are so hopeful of getting money. It's also obvious that it has to be countries with a large population
I think the statistic is not accurate because we do not know each country's situation and how people react with gambling games.
But I agree that in poor countries, people tend to play gambling because they think gambling can give them money by playing traditional gambling games, making traditional gambling games very popular in those countries.
Maybe in the other country, gambling games are popular because whether we agree or not, gambling games can tempt them to come and play many gambling games.
Their mind will think that gambling is a good way to make money, but they are not right to think like that.
