this other website tell a slightly different story
Nope, if you will pay attention they are not totally different. Try to look on the statistics on 2014 found in this website and then compare it to the first list you've mentioned. They are almost the same isn't it? Thiugh the article on thr first one was published last 2017, there is no content saying when the statistics exactly conducted. Maybe it was on 2014 as well, who knows. I t comes as a big surprised that Australia are gambling the most they are always on top in the gambling stats, I guess it's easy because their people can afford to gamble and so many people them like to be entertained, Australian are like that always want to have fun by drinking and gambling.
Me too. I never thought that Aussies love burning money huh jk 
. But seriously, I didn't expect that. I thought Americans and the Chinese will constantly dominate when it comes to this because they got the largest casinos in the whole world. Or they most of them are just good gamblers?
