Any linux process can run with elevated privileges (ie: as root) by setting a specific permission bit - https://en.wikipedia.org/wiki/Setuid. This is used for many things like ping and sudo.
Instead Run0 is using systemd to elevate privileges.
There is a lot that could be said, but suffice to say you can have both sudo and Run0 installed. So even if a Distro ships Run0 by default, you can always manually install sudo.
