Some programs may use libraries or tools specific to a distributions package manager. For example, yay, an AUR helper/pacman wrapper. You would have a very hard time getting it to work on Debian.
Other programs might only include build scripts for a distro specific build system. For example, a program might skip using a Makefile, and do everything in the Arch-specific PKGBUILD.
Generally though, most software uses a standard cross-distro (or even OS) build system. In this case, compiling from source would be an option on any distro. The program might still only be packaged for Arch/NixOS/Gentoo (or others), as it is a very simple process to do so.
