Windows has had one or two that I've seen, but not common, and I don't hear every Windows user swearing by them. Linux has GnomeDo, but I found it lacking, and again I haven't heard people swearing by them. ChromeOS has one I think, but I can't remember the name, and again it doesn't seem popular.
macOS on the other hand has had Quicksilver, Launchbar, Alfred, and Raycast, to name just those that I've personally used, and Spotlight has been built in to macOS for a long time, with a launcher/utility interface for many years. I've also heard many people (at least in techie/knowledge worker circles) using them, and have met strong proponents of all of these options.
Is this difference just down to my lack of knowledge of other platforms, or is there a grain of truth to this? If so, why? What makes macOS conducive to this (is it that these are all built on Spotlight and therefore can exist easily), and do users just demand this more on macOS?
