how can i upgrade x os10.11 to os13.00

Hi,

A Mac that can run 10.11 cannot run 13/Ventura. If you have a Mac mini, it would need to be a 2018 or newer model: macOS Ventura Preview - Apple

Back up your data, check your applications for compatibility, click here, and if your Mac mini is a mid-2010 or newer model, then on the download link for High Sierra.
