Your files shouldn't be erased. Mine weren't during the Catalina upgrade or previous upgrades. BUT you should have a backup just in case something goes wrong. That applies all of the time and even more so when doing an upgrade. The following may also help: How to upgrade to macOS Catalina - Apple Support
