What do I even do?

I have 2 apps on my phone that I use, the rest aren’t able to be deleted, and yet I am unable to update them due to “iOS” and “System Data” taking up all of my storage. What am I supposed to do? Is there any way to clear any of the storage taken up by the System Data? I can’t afford a new phone. Phones like this used to be able to hold tons of apps, now I can barely have 2.
