The documentation is vague on purpose - due to the variety of platforms

GetTickCount, we do not want to guarantee specific units (GetTickCount is
supposed to be supported directly by the
platform rather than having an additional RTL layer possibly unifying
differences in platform behaviour on top of it).
IMO the result of GetTickCount without defined measure units is useless.
Each his opinion.
For example, I think GetTickCount is utterly useless.
I have never used it, never will and I have nevertheless already done
plenty of time measurements.
Depending on the platform, gettickcount falls back on Now(). This does not have
a
millisecond precision. This call can take a time of up to 90 ms.
So saying that gettickcount has millisecond precision would be simply
incorrect.
What I will do is explain in the documentation why the units are not
mentioned.
