Do I need strong mathematical bases to work in the memory subsystem?

Actually yes

Linus has a Masters in Comp Sci, not that he is the greatest engineer ever.

I can't testify to that, but there are ton of Master Degree coders and a
lot of mathamaticians.

General plumbing is not needed, but predictive trees, and crypto
certainly do and some hardware problems need calc, or even integration.

The harder the job, the more math is needed.

Maybe, but I don't think so.  And the hardware is getting more exotic.
