Incorrect, only some UUIDs are random, specifically v4 and v7 (v7 uses time as well).

This would technically be version 2, which would be built from the date-time and MAC address, and DCE security version.

But overall, if you allow any yahoo to pick a UUID, its not really a UUID, its just some random string that looks like one.

Which is to say, not guaranteed at all. GUIDs are designed to be unique, not random/unpredictable
