It just means the remnants of the Big Bang that mostly created hydrogen, helium, and lithium. There’s nothing particularly special about it other than the possibility that it is as old as creation because there are stable isotopes.

All of the hydrogen was created at the initial cooling of the big bang. In this case what I mean by primordial, is that it was never part of a larger composite object like a star.
