Wrong.  If two things are mutually exclusive that does mean that you
can have either the one, or the other, but not both at the same time.

I can't imagine any situation in which two skill sets could be mutually
exclusive, since that would mean that knowing one set of skills would
actually prevent you from knowing the other set of skills, which would
be very strange indeed.
(Knowing how to ski does not prevent you from knowing how to drive, and
knowing how to drive does not prevent from knowing how to ski, thus
they are not mutually exclusive skills.)

What you apparently tried to convey was that the skill sets are
"completely separate", "non-overlapping", or "independent of each
other".  None of which is equivalent to "mutually exclusive".
(If the skill sets in question actually are independent of each other
or not, is a question that I will leave for you to discuss.)

Here endeth todays English lesson.
