If I import a library in a notebook, will it be available for everyone using the cluster?

No. If you use %pip or %conda to attach a library, then it will only affect the execution of the notebook. A separate virtualenv is created for each notebook and its dependencies, even on a shared cluster.

If you create a Library in the workspace and attach it to the cluster in the cluster UI, then that does affect all users of the cluster.
