Remember that electrons can have angular momentum in the atom! If angular momentum is 0, of course we get a spherically symmetric probability distribution.

But if the electron has angular momentum it must be, in some sense, rotating, so we have to pick an axis. Our probability distribution should be cylindrically symmetric, but it won't be spherical anymore.
