ELI5: What is the difference between the Classical concept of full employment and Keynesian concept of full employment

I am having a hard time on understanding the concept. I have minimal knowledge on economics and I am seeking here for an explanation about this. Thank you people.

In classical full employment, everyone has a job. In Keynesian full employment, everyone who wants a job has a job. If someone is moving from a Walmart stocker to spaceX engineer, it’s probably a good thing that they were unemployed for a month.
