I guess it could be a regional thing, but for the most part i'd be inclined to say yes.
Most of the larger cloud vendors offer managed Kubernetes in one way or another (Azure, GCP, AWS, Scaleway etc.), which you cannot say about any other orchestrator out there.
Most of the large enteprises that i've worked with also are moving towards introducing Kubernetes internally, sometimes with pretty large clusters for multiple projects at once!
Similarly, most of the tooling out there is focused on Kubernetes nowadays (networking, storage, deployment solutions), which isn't the case for other orchestrators.
Of course, many out there don't even need an orchestrator - Docker or even Docker Compose (or the podman equivalents, or other solutions like that) are oftentimes enough for smaller scale projects, it can be a while before you would enjoy the benefits from the likes of Docker Swarm, Hashicorp Nomad or even one of the many Kubernetes distros out there. Once you need to scale past one (or a few servers) and need to orchestrate deployments across all of them, it might just be worth to look into them, though.
