Well, it came from... Sony, their creators!
PSX was the codename for the original model. It was spread even before it was launched. PS One was the PlayStation "Slim".

I'm in the complete opposite side of this spectrum. I just feel apathy towards people who call the PSX "PS1", even though I am not sure if they're talking about the real PS One or just being ignorant.
They could have also left the media out. I'm sure misinformation is spread through all messenger apps.
Nothing new here. PS3 games were famous for requiring an install from the optical media to the internal drive first, and then also downloading some mandatory major update before running. The role of the physical media was mostly symbolic.
That's precisely the PSX.
