Is number of photons greater or energy of each photon?
the number of photons per second per watt of power is a lot greater for UVC than for gamma radiation.
If the number of photons per Joule* is higher for UVC, that means that each photon carries less energy.
*A Watt is a Joule per second; sustaining a Watt of power for one second requires a Joule of energy.
