ELI5: How does your brain do complex calculus and physics calculations to determine trajectory, velocity, and acceleration of objects you see (like catching a football) without using numbers or variables?

It doesn't.

Our brains are very good at pattern-matching and extrapolating from previous experience how things will behave. We don't calculate the trajectory so much as just compare to our previous experience and guess about how it will behave under the conditions. We aren't calculating so much as thinking it will "kinda sorta do that".
