Like some have pointed out this means nothing.
For all we know Amazon sales charts might not even reflect the true ranking order of their own sales. Some retailers have a habit of artificially putting a new release higher on a sales top list (albeit for a brief time), just as a way to draw attention to it and in hope of making it appear more attractive. I don't know for a fact that Amazon does it but from history we know that their sales charts deviate radically from the charts of tracking services.
