Technically it's a fan-made fictional character, so I do believe it fits the definition of "fan fiction", just like pretty much every sheet made on this Wiki. But it's true a Sue is mostly defined by narrative favoritism, which cannot possibly exist here since there is no story in the place, as you mentioned.
