Yeah, but finance people (way after the roman times) adopted M as a suffix for thousands, and once you treat it as a suffix or prefix it made sense (to them) to use MM for million. You sometimes see the same done in engineering-adjacent contexts with SI prefixes, like using kk for million.

The finance people that I know uses K for thousands and MM for million.
Tech and science use K for thousand and M for million.
Using K and MM in finance reduces the odds of an incorrect interpretation of a single M.
