I think that's a correct statement. And, to be honest, because of
exactly that, I've long since given up, trying to even remotely grasp
how much memory a process on my Unix systems consumes.

On the client side, the prime example against being able to understand
is Chrome; on the server side, it can be server processes like php-fpm,
Apache or whatnot.

Bottom line (for me): It's basically close to impossible to understand
this.
