however, if it is about online gambling, may be many people here are also playing it. But not in the real casino or offline casinos.
I doubt there would be accurate table and statistics here in online ganbling as most of us plays anonymously
Of course! In many countries gambling is prohibited by law, but people continue to play online using VPN or TOR to bypass bans. It is simply unreal to collect statistics on these players and also on the whole world. So in my opinion these statistics are far from the truth or reflects the situation only in the gambling houses excluding online gambling.
I am not sure that the statistics indicated by the author take into account gambling sites and bets in them. Still, this is a rather specific destination without a visa, which does not depend on the visit of citizens of one country. the growth of the national segment of online games differs from other large countries.
