It's how to get it back to brand new right out of the store. You will be downloading your stock files from that page under the video, don't use your backup. It's about 1.5 gig file, use a Pc to download it, you don't want any errors by doing it through your phone. Make sure you choose your T-Mobile zip.
If you want to reset your flash/binary counter follow those links first. Important if you need to ever return the phone, if you don't plan on rerooting you might want to think about doing that.
When you Odin this file to your phone its going to wipe everything off your internal, roms, backups, twrp, music, photos, everything, so if there's anything you need off it back it up somewhere else other than the internal storage.
Follow the instructions to the letter, there's no shortcuts or unnecessary steps.
