Incorrect, that was a trap I set for you, actually they (the
sudo) are not needed at all. and you fell for it!
BTW I learned that method when I catched wild animals with my
bare hands - for survival.

I confirm here and now that

  (shell-command "setfont Lat7-TerminusBold16")
  (shell-command "setfont matrix.fnt")

works great.

$ ls -l /bin/setfont
-rwsr-sr-x 1 root root 60112 2020-10-11 12:13 /bin/setfont
