The Higgs theory does explain why the force particles (photon, W, and Z) have the masses they do, but it doesn’t generally explain why the matter particles have different masses (why some interact with the Higgs field a lot and others don’t). There is probably a pattern to the masses, but it’s one that has so far escaped us. Our level of sophistication is just like Ook and Groog’s, who explained things by listing them. In the same way, our best theory of the universe only lists the masses of the matter particles as arbitrary numbers.
