I don't know why it is so difficult to read the manual pages % man su If group 0 (normally ``wheel'') has users listed then only those users can su to ``root''. It is not sufficient to change a user's /etc/passwd entry to add them to the ``wheel'' group; they must explicitly be listed in /etc/group. If no one is in the ``wheel'' group, it is ignored, and anyone who knows the root password is permitted to su to ``root''.
