Export/Import Sublime Text 3 Configuration Across Two different Apple Computers
Your question is a bit unclear the way it is worded, so hopefully I got the gist of it.

If you already have a license for Sublime text (or it is share/freeware), then yes all you have to do is copy it from one Mac to another. You can do this with thumb drives, over the network or just download a fresh copy from the developer's web site.

You are not "creating" an app, you are just copying it.

If you check the developer's web site it should indicate what version(s) of macOS the app you have is compatible with. You may need to know what version you have (Sublime Text menu > About Sublime Text) as often different versions are compatible with only some versions of macOS.
