Process namespaces and hidepid both place restrictions on processes seeing each other, as can security modules. Unsure if that's what they're referring to and don't feel like trying to find that in a video.

I'd understand that from normal users but root on Linux should show all pids (or have an option to show them).
Yeah, need more info on this to understand fully.
Watching video now but don't really want it scan back to find it either.

Unconstrained root in the top-level namespace can see all the processes. There isn't necessarily any actual root on a system after early boot since root can restrict itself with MAC/MLS via security modules, or could set up namespaces and enter those without staying in top level.
