Note: Github is primarily made for developers to share code with eachother. Distributing ready-to-use-programs to end users is an afterthought and is not intuitive for the public.

Look for the release page on the right window; good chance there are .exe files or similar bundled downloads available.

If no releases exist and you just want to get the files you see in the source overview, use the green “Code” button and download as zip. This will usually not work if you are downloading a program that needs to be executed.

If you only want to download one single file, use the “download raw file” button. This also only works for programs that dont need to be compiled. If in doubt, contact the developer.
