Kinda but not really. Apple have been running a version of macOS on ARM since 2007. You know it as "iPhone". So they had a big head start moving into the desktop space. But ARM -- Acorn RISC Machine -- has been around since the 1980s, predominantly in the "pocket" computing space: PDAs and mobile phones. Symbian, from the early 2000s, is one of the best but yes, Microsoft dabbled in ARM with Windows/CE. It... wasn't one of the best.
Linux kernel has had ARM support since before iPhone's launch because Android among others, but its been steadily gaining traction in the server space starting with credit card boards like Raspberry Pi and expanding into proper rack-mount servers. Pick a distro with an ARM port and it's going to run mostly the same as it does on AMD64.
Microsoft Windows... is an outlier. Partially because Microsoft largely abandoned everything but AMD64 after Xbox 360 (PowerPC), partially because of their half-baked dive into progressive web apps. Probably other reasons as well but long story short, Microsoft are playing catch-up to the rest of the industry.
