Wouldn’t Ryu’s high output make him instantly run out of cursed energy and get on tapped?

Ryu has the highest output in jjk and his ct is just beams of compressed cursed energy, so wouldn’t he just run out of cursed energy and get killed after a few powerful blasts?

It doesn’t make that much sense to me cuz he’s never stated to have tons of cursed energy or a super fast cursed energy recovery rate.
