I'm actually not a huge fan of pain compliance techniques. They have their place, but they're not that reliable. A good wrestler/judoka/BJJer can control an opponent through the manipulation of balance, application of leverage, placement of weight, and the use of good body structure, without relying on pain to enforce compliance. In my experience, that approach is much more reliable.
In the Hapkido I learned, we used a variety of pressure points and joint locks, all of which caused pain, and in the case of joint locks, gave control or broke things depending on how far we carried it. Pressure points are different. A proper joint lock should hurt anyone if done correctly. I have found that some pressure points don't work the same for all people, if at all. But frankly, those people are in a small minority. Usually, a properly applied pressure point will cause pain. But again, as we learned pain pressure points, they were mostly to facilitate a technique.
All that to say joint locks, properly applied should work on anyone. If it wasn't properly applied, or your opponent knows a counter, you need to disengage quickly and try something else.
