It is not unbelievable but it is not the case, simple as that. If VGChartz numbers are anything near right then 33% of people who have purchased the game are playine online which sounds about right. If a lot of people are playing online then VGChartz could very well be overtracking.
I think the way the stats work is that if one plays 3v3, 6 human players are counted. This keeps going on so that probably is the case.
