I wonder how Macau is not a part of any of these two lists!! Macau is a country whose economy is based on gambling businesses where 40% of their GDP is delivered by gambling! But these are really land based casinos which means the numbers here show the tip of the iceberg. Due to the social taboos around the world, a lot of people don't really visit the land based casino and these group of people actually enjoys the online casinos from the comfort of their home! And it is really difficult to capture that number correctly!

Secondly, I see US is missing from the list as well! US has an entire city for gambling and it is a prime destination of gamblers and tourists from around the world. I am sure everyone wants to visit Las Vegas at least once in their life! So I seriously feel the list is flawed!
