/proc is not a real filesystem that consumes disk space.
It's the list of processes on the machine and the information
about them. The /usr/bin/ps command reads from all those
directories and files under /proc in order to display the
list of processes to you.

Another way of saying it is that the /proc "filesystem" is
just a way of viewing the kernel's information about all the
currently running processes.
