Everyone can use ping. A user always (with appropriate permissions) can execute binaries with specifying the
absolute path, even if the binary is not in his PATH. e.g /usr/sbin/ping, except for when he's jailed in a restricted shell.
Then he would get something like
bash: /usr/sbin/ping: restricted: cannot specify `/' in command names
Besides that, special privileges can be given to users with "sudo", but in case of ping, thats not necessary.
