Submarines are giant pressure vessels made to withstand a lot of force from water. That likely makes them resistant to the size of munitions a drone could carry when detonated externally. However, it being a pressure vessel means that any munitions detonated inside could be very deadly for the crew. Explosives can kill primarily by propelling shrapnel outward or by causing a pressure wave intense enough to shred sensitive tissues like lungs. An enclosed space restricts how a pressure wave can expand and increases the distance at which a modest explosion can kill. So, those in the submarine would want to take care to make sure a drone can’t get inside the submarine before detonating.
I’m not a subject matter expert, and this is largely speculation. I did once watch a special about a group developing a powder dispersing bomb that would send a lethal pressure wave deep into cave/tunnel systems.
