There are countries that restrict their citizens from gambling, and if anyone is caught gambling, that person will bear the consequences of breaking the law. So countries that have fair and solid gambling laws protecting their players will have more gamblers than countries that restrict their citizens from gambling because they know there is no law stopping them from gambling and they will not face any law if they gamble. Poverty can also be another factor that can influence country A to have more gamblers than country B because, since country A is poorer than country B, country A will gamble more that country B so that they can escape poverty.
