You don't need uzumaki chakra reserves and mountain busting attacks to best your opponent. Itachi can stream amaterasu not just fire it. He also has genjustu tactics and intelligence that allow him to make up for his weaknesses. Itachi also overlays attacks. Stamina isn't the only determining factor of a battle, because by that logic itachi is the weakest character in naruto.
