The situation is much different for gamers. They might have been thinking of the Steam survey where Windows does in fact have 95% adoption:

Interestingly, the percent of Windows goes down if you look at just the United States, where it's only 63% of OSes. And it also goes down similarly when you set it to the UK, or North America, or almost any other region. But it goes up to around 73% when you limit it to Europe or Asia. Weird, why is it higher in those areas?
