Trying to Update Macbook, Not enough Storage

I’ve been trying to update my Macbook pro for a while now. I’m on version 10.14.6, I’ve been able to get away with not having enough storage for the newer updates but now it is unavoidable as my laptop is nearly unusable.

My issue is that I do not have enough storage. I’ve done everything, deleted old files, cleared my trash, deleted apps, etc. Still, the two things taking up the majority of my storage are applications the laptop will not let me delete and the system itself. It’s become incredibly frustrating, especially since the majority of the apps that I can’t delete I don’t even use. Is there a way to bypass this? Or any other possible solution?
