True.  But also, /etc/sudoers should not be readable by
anyone other than root:

On f37:

    $ rpm -qlv sudo | grep /etc/sudoers$
    -r--r----- 1 root root  4375 Mar  1  2023 /etc/sudoers

If you have edited the file manually, your editor may have
screwed up the mode.  You should use visudo to edit the
file, generally.
