MM is a common abbreviation for millions in finance and accounting. Not usually used colloquially, but it’s not wrong.
M is roman numerals for thousands, so MM is a thousand thousands = million.

In finance and accounting, MM (or lowercase “mm”) commonly denotes that the units of figures presented are in millions. The Roman numeral M denotes thousands. In this context, MM is the same as writing “M multiplied by M,” which is equal to “1,000 times 1,000,” which equals 1,000,000 (one million).

While Roman numerals are technically additive (MM is really 1,000 plus 1,000 or 2,000), MM is still a fairly common way of abbreviating millions, especially in certain industries like oil and gas. This guide will explore how the notation should be used, as well as alternative symbols that are used in practice.

I think this says that IF MM is to be interpreted as roman numerals, then MM is additive and means two thousand, whereas IF MM is to be interpreted as the ad hoc finance unit, then it denotes millions
M also denotes the metric prefix Mega, which means a million of something.
