The answer to the question I think you're asking is "yes".

More precisely, it is the upper bound for the process group under the
login process, which execs a shell AFAICS.  fork(2) will inherit the
current resource limits AFAICT from the man page.

So /etc/security/limits.conf will affect all children of the login
shell, but any ulimit's done in the login shell will propagate to its
children, any ulimits they do will propagate to theirs, etc.

Of course if any of those children suid root then all limits are off.
