The source of that "statistic" is sharenator.com, which seems to be basically a self-reporting traffic analyzer. That means that it does not analyze traffic from server or packet statistics. Much like alexa it would seem to gather visits from a narrow demographic (those who sign up for sharenator/alexa kind of websites) and extrapolates to the entire demographic using the web. That's dubious at best; it's not real and is therefore basically useless.
But people will draw conclusions from it and speculate endlessly based on it, believing in it implicitly. Then they will elsewhere make very sarcastic remarks about "statistics".
