Because they have different ears of course !

Well yes, but the differences in the brains are at least as large.

Listener training has a huge effect on listener sensitivity.

I have worked with people who initially could not sense a difference at all,
but rather quickly learned how to achieve at least typical levels of
sensitivity. BTW, ABX tests are very helpful for conducting this kind of
training.
