That is indeed the point that is typically made. But *my* point is
that if you turn the question round, and ask, not how many aquatic
mammals are hairless (very few), but how many hairless mammals are
aquatic, you get a different answer (most of them).

The real underlying point is that fur is extremely valuable to
mammals; they abandon it rarely. When they do, it is usually in water.
