As far as I know, gambling places can only be prohibited in several countries that have regulations regarding gambling businesses. There are 30 countries that strictly prohibit gambling in their countries and there are also several countries that provide permits for gambling businesses which you can find in Las Vegas, Nevada. , United States, Atlantic City, New Jersey, Bahamas, Puerto Rico, Mauritius, Seychelles and Macau (Correct Me If I'm Wrong). So, if you already have children and in your country there are no prohibitions on gambling, what you can do is set limits on the use of gambling sites via smartphone or the network used and be given advice about the dangers of gambling and the benefits of gambling which are only momentary.
