No, this is not necessarily true. It depends on the vulnerability the
virus/worm utilizes.

A virus/worm that runs in user context (such as one an unwitting user
clicks on and executes via email, or certain buffer overflow exploits
of programs run in local user context) won't be able to overwrite
system files or registry keys that a limited user is not authorized to
modify, and as such, will fail in the general case to infect the
entire system.

That's the modicum of additional security that a limited account
affords ya.

You would be correct only if speaking about the subset of malware that
attacks unpatched vulnerabilities of system processes that run with
system privileges.
