Good job learning the basics of Kubernetes!
It is a good idea to turn off kubernetes mode in docker-desktop when you are done.
There are still many things we did not cover

- Network policy
- ConfigMap
- Secret
- Resource limits & requests
- Persistent Volumes & Claims
- and more
Not overwhelmed yet ? Take a look at CNCF landscape
