Full-stack course = front-end + back-end course?

I am wondering if the full stack course consists of the content from front-end and back-end course?
To be clear: I am not asking what front/back end means. I am asking if there’s something more in separately front-end and back-end courses than what is there in a full-stack course.

The full-stack probably does have all the same things as the front and back end combined BUT it the indivisible courses probably go into more detail compared to the full stack.
