You are being fazed by two different, annoying things.

Even in physics itself, the word "mass" has multiple contexts (inertial, gravitational, and conversion to energy) in which it is used. Einstein made quite a lot of hay out of relating the three. "Entropy," too, has multiple contexts.

The second thing possibly tripping you up is the tendency for scientific terms to be poorly appropriated into a new context, like "theory." You can fight this but it is a losing battle, so I typically just try to set it aside.

A borrowed term in another context is not the same as generalization. Read my responses again.

I think my first comment was clear enough about it without needing to step into semantics.
