From further down the page, he explains how he got those numbers:
"I logged intenet traffic, and extrapolated the data, therefore it's not entirely original. It's impossible at the moment to actually get *real* up-to-the-date numbers for every game, as some game's leaderboards are refreshed deleting every gamercard that's played the game, and some don't reveal, or make finding numbers, easy."
Seems kinda sketchy to me, but I really know nothing about the method he describes.
