Sure, sudo does use elevated privileges (but that's not unique to sudo, e.g. mount does also), but the command that you call i.e. command in sudo command may not (depending on what is set in /etc/sudoers).

@aragilar yes sudo does not always give elevated privileges, but it does run at elevated privileges, after doing its thing (checking authentication, it may drop privileges). It needs these elevated privileges to be able to change user.
