I just bought a second-hand 16 inch 2021 MacBook Pro M1 with 16gb of RAM and 512 GB of SSD. I have reinstalled the newer version of MacOs (Monterey 12.6.6.) and erased the whole SSD. I did not download anything on my Mac so far, but MacOs and System Data already take up 16 and 20 GB of storage respectively. Is it okay? I have already checked the Cashes folder, with no file weighing more than 10MB.
MacBook Pro (2021)

To compare this computer came with mcOS 11 Big Sur and was upgraded to macOS 12 Monterey and now sitting on macOS 13 Ventura 13.4 ( latest Version )
