You can't just compare fighters to each other in a fair way, combat is not fair. There will be assets supporting both air forces, and key way to beat Indian air force is to destroy AWACS aircraft. Without AWACS, IAF would be like a man armed with a gun, but only has a flashlight at night while PAF would be able to operate with night vision goggles. J-10C is not the key here, it can't perform the role needed to destroy AWACS at far range.
Key for PAF is buying an aircraft like Mig-31BM armed with very long range BVRAAMs that allow engagement of AWACS at far ranges, and yet can safely maneuver out of the situation. Even buying a squadron of these aircraft would allow PAF to take out strategic assets of IAF.
