It does. Upstream kubeadm - authentic kubernetes - can even run on a single node. Not sure why people choose k3s or microk8s when you can just as easily deploy the real thing.

For smaller needs, K3s runs fast/stable on servers with 1-2 GB of RAM, whereas K8s proper tends to be a little shaky until you go to 2-4 GB, minimum.

I hear this a lot but have any actual, tangible comparisons been done with k3s vs kubeadm arm resource use?

That's exactly what i am confused about when only reading these things in isolation.

kubeadm is very bare bones though; it gives you a running node but you are still responsible for configuring network and storage providers, an ingress controller and probably a load balancer.
