Indeed, if we have concepts about the real world and it is not possible to cast them into rigorous mathematical form, that is usually an indicator that some aspects of these concepts have not been well understood.

Theoretical physical aims at casting these concepts into mathematical language.
Theoretical physics aims at casting these concepts into mathematical language.
But then, mathematics is just that: it is just a language.
If we want to extract physical conclusions from this formulation, we must interpret the language.
That is not the purpose or task of mathematics, that is the task of physicists.
