Yes but that's training time. At runtime AlphaZero got magnitudes more computation power than stockfish. A more fair comparison would be use as much computation needed for training but for runtime, use equal wattage hardware. E.g 20W of cpu in mobile phone running stockfish to 20W of GPU in nvidia TX2 running AlphaZero to 20W human brain.
