A few things. 1) teach you to learn and work hard. 2) teach you things that have high cost to learn/barrier to entry. You need a lab etc. 3) mentoring 4) give you required/legal papers to practice a craft.
Basically if your education doesnt teach you high level math, requires a lab or gives you legal ability to do some job, you could probably have learned the thing faster by yourself. If you know how to work hard.
If the above isnt part of the subject you study its also unlikely to learn you how to work hard.
Some educations might also provide competition that will push you.
If anyone noticed these education are pretty much only STEM.
Finally when getting your first job employeers often want "proof" that you learned something or at least have to ability to complete something.
Chatgpt is a tool and it does what its good at very well.
It wont replace deep quality work, but it will speed you up.
Ive found it really usefull when I need to find documentation and its also really good a writing scripts. Probably not better than me if I knew Bash, but I dont use I often enough to be good at it.
