I had about 83 GB before I installed Xcode, I was in the middle of the installation and reconsidered my decision but it's still stuck on 73 GB, any ideas or ways I could probably get my lost space back even though there are no files/folders or applications for Xcode, so I don't know what it is. Thank you!
You can try downloading some kind of computer cleaner like CleanMyMac X free version, also definitely restart your computer if you haven't done so already.
