That's more of a historical artifact. The BSDs started as a set of patches for AT&T Unix that were _distributed_ by Berkeley. Eventually they became an entire operating system. _Then_ the various BSDs that we know today (FreeBSD, OpenBSD, NetBSD, DragonflyBSD) all forked and became completely independent operating systems. For decades, FreeBSD's kernel and userland has been developed independently from the OpenBSD kernel and userland which is developed independently from NetBSD's kernel and userland, etc. You could not take an OpenBSD program and run it on FreeBSD. Even recompilation from source isn't necessarily enough since the BSDs support different syscalls.
They are completely independent operating systems with a distant shared history.
Whereas on Linux, the distros are taking a common Linux kernel source, and combining it with their choice of common userlands like GNU. Debian has the same kernel and GNU userland that Arch and Fedora use. That is how Linux distros are "distros" whereas the BSDs are independent operating systems.
While you’re correct that FreeBSD is not a Linux distribution, the word “distro” is literally short for distribution. It doesn’t have a different meaning like smart and smartass, it’s more like repo and repository.
What does the D in BSD stand for again?

Distribution. Which is a different word than distro, with a different meaning. Like smart and smartass.

Distribution. But it’s not a Linux distribution.
