Yes, all of the items in the battery usage list should add up to 100% (probably a typo somewhere in the OP, but that's irrelevant). If Android system was responsible for 90% of the battery drain and the battery has drained 90%, then the Android system has used 0.9 x 0.9 = 0.81 or 81% of the battery.
