nodes and probability density
The text is simplifying, as what it says is valid for and only for 1s orbital.
The text author had probably in mind that there is no sharp end of electron density as misinterpretation of orbital shapes may suggest. There is an asymptotic exponential-like ceasing of the wave function values toward infinity.
All higher s orbitals with n&gt;1 have n-1 radial nodes, having zero $|\Psi|^2$ value of wave function at n-1 different radii.
Similarly, 2p orbitals have the node plane passing the center between the two lobes and upper p orbitals have additional node surfaces. Similar for d and f orbitals.
