If protease digests proteins into simpler substances,then why won't it digest itself, since protease is an enzyme and enzymes are made up of proteins? At that, will it digest other enzymes as well?

At high concentrations, the protease molecules will hydolyze (digest each other), but as the concentration of undigested surviving protease molecules decreases, the number of collisions between protease molecules becomes less and less frequent so some protease molecules will always survive.
