If I set 3 threads to wait for a mutex to be release, do they form a queue based on the order they requested it in or is it undefined behaviour (i.e. we don’t know which one will pick it up first)?

It is explicitly documented in the SDK article:
These kind of events are entirely out of your control. So “undefined behavior” is an appropriate way to describe it.
