iPad 10 (2022) 64gb available storage

I'm thinking about buying an iPad 10 64 GB this year and I was wondering that if this version would be sufficient for me. I would use it for studying purposes, like watching online classes, reading PDFs, and taking notes. I know that the system takes up some space, so I would like to know how much of it it takes and how much of storage is left for installing apps, putting PDF files and making notebooks. Thanks in advance.
