I wondered about this too. It's not a point, though, that doesn't make sense in QM. So do they mean that the wave function is totally spherical?

Plus I want to point out that it's pointless to say that something is spherical to within 1e-20m unless you also say what the "radius" is. If the radius is 1e-21m it's not a very good sphere at all...

Why doesn't a point make sense in QM? Electrons are point particles - they have no size at all.
