Amazon's own best-selling tracking system shows very different numbers from the website you were probably using (ranktracer) - I would personally trust what Amazon reports as Amazon's numbers more than what another website reports as Amazon's numbers. Of course, your preference may differ.
In any case, this just goes to show you can find 100 different sources to pull out of your hat, @$$ or wherever numbers and statistics just to fit your, or anyone else's, argument.
I wouldn't trust any of these stats anyhow, as they are too narrow a sample. Amazon is not the only place on earth to shop for consoles, you know.
