It's debatable whether or not non-shinobi even have chakra in the first place. Still, Rachin123 has a point. There's still the missing nin, shinobi who might've stayed behind to guard their respective village, ninja villages who didn't participate in the war(E.g. the hidden rain village), animal summonings, and possibly more.
