The model year of a MacBook Pro is available at Apple menu > About This Mac.

A mid-2010 through late-2011 MacBook Pro can be upgraded to High Sierra 10.13.6 but no later version.

A mid-2012 through early-2013 MacBook Pro can be upgraded to Catalina 10.15.7. See: https://support.apple.com/en-us/HT211683

A late-2013 or later can be upgraded to the current version of Big Sur. See: https://support.apple.com/en-us/HT201475

Back up your data, check your applications for compatibility, and depending on which MacBook Pro model you have, click on High Sierra, Mojave, Catalina, or Big Sur.

Sierra is 10.12, not 10.13. If you're currently on High Sierra, your computer will need to be a 2012 or newer one to be upgraded.
