I'm no expert, but while that sounds like a proper size for your Player files, your World files seem incredibly undersized, unless they are Small world sizes. So, if they're not, something's gone wrong with your world. If they ARE Small sized worlds, then ... Make backups of that folder -- My Games\Terraria, and reinstall the game. That might work?
