Yes the Schrodinger Wave Equation (SWE) is deterministic but that doesn't
matter because it describes nothing observable in the universe. To figure
out if a electron will be at point X you've got to square the value of the
SWE at point X , and then all you get is a probability not a certainty. To
make matters worse the SWE uses imaginary numbers so 2 very different
complex numbers provided by Schrodinger can produce identical probabilities
after squaring. If 2 different things can produce identical results then
things are not deterministic, and if those results are probabilities not
certainties then things are even less deterministic.
