OS - 32 bit or 64 bit?

I have the Macbook Air Pro 13-inch, M1 (2020)

MacOS Big Sur, Version 11.6

I clicked on "About this computer" and I can't find the answer anywhere to one simple question:

Is the operating system 32-bit or 64-bit?

I also printed out a spec sheet that I got from Apple, online, and there's nothing about it.

Why does Apple make it so hard to find the answer to what I consider to be a simple, basic question about the specs?

All Mac operating systems have been 64 bit for over a decade.

Starting with Catalina, the MacOS will only run 64 bit apps. Prior to Catalina, the MacOS could run both 32 and 64 bit apps.
