Yes, you've touched on a key difference between Jenkins and GitLab in general:

Jenkins: only does CI/CD, needs to be integrated with a suite of other tools.

GitLab: end-to-end DevOps in one application that has native project planning, source code management, CI/CD, artifact repository, configuration management, and observability built-in.

So Jenkins-X Serverless is about the Jenkins service itself running in a serverless paradigm. Or "using Knative to run Jenkins"

GitLab Serverless is a configuration management feature that allows you to build, deploy, and manage your own serverless functions from the same place where your issues, code, artifacts, etc. are. Or "Using GitLab (which uses Knative) to run your functions."

Jenkins-X adds a bunch of stuff to Jenkins including an artifact repository, a helm chart repository, release management, et cetera. It's pretty cool.
