How come? Boltzman stat.

Because the two derivations provided at your reference work!

"...most systems at high temperatures obey the classical (Maxwell–Boltzmann) limit unless they have a very high density, as for a white dwarf. Both Fermi–Dirac and Bose–Einstein become Maxwell–Boltzmann statistics at high temperature or at low concentration..."

It also depends on what your mean by "correct"...."approximately correct" would perhaps be a better description.... did you see the "limits of applicability"...??
