Yes, but the whole point is that this is a top selling app among many thousands, and it's only making $80,000. I would guess if you take the average selling app of its category, you would find that it's making much less than $40,000. That said, unless this is a massively complex app (which I doubt), it really should take much less than a developer man-year. Plus, I'm guessing that this $80,000 is the net revenue, after they've paid their developers. Still, it's not exactly inspiring for those of us starting to do mobile app development.
