Many defensive gun uses (DGUs) never get tracked as such. From personal experience, I have pulled a gun on another human being one time in my entire life. I was legally justified, and the aggressor stopped, lowered his gun, and left. My one defensive gun use was never recorded as a stat anywhere as far as I know, because no shots were fired.

My wife has used a firearm in self-defense twice in her life. Once on somebody who was acting very rapey, who suddenly found a better place to be when she stuck a pistol in his face, and again years later on a German Shepherd that was attacking my one-year-old son. No police report at all on the second one, and I don’t believe the first one ever turned up as any sort of defensive use statistic because no shots were fired.
