The term "Submarine" is simply a joining of the 2 words "Sub", meaning "below or under", and "Marine", meaning "of or relating to the sea". So, Submarine literally means, "Under the Sea" or ocean.
Humans have problems diving to extreme depth. SCUBA by definition is self contained and cannot get close to the life support potential of submarines. Specialist submarines like the bathyscaphe can reach the deepest parts of our oceans.
ROV stands for "Remote Operated Vehicle". ROV's are not submarines by definition, since they are robots controlled by tether, by an operator stationed on a support vessel.
