Well, right tool for the job. So 90% of the time math is used in physics to either calculate some quantity, like a scattering amplitude or the position of a planet, or to build models. In both cases you are right. But there is the entire area of mathematical physics, where the goal is formal proofs. ( Admittedly, mathematical physicists are quite often more in the business to get in the position of being able to write down a formal proof, rather than actually proving theorems. )
