Yep, looks like Apple added this in Ventura:
https://www.apple.com/macos/ventura/features/Image search:
Spotlight uses information from images in Photos, Messages, Notes, and the Finder to enable searching by locations, scenes, or even things in the images, like text, a dog, or a car.
So I guess this is what you are seeing. I took a look at your account and it seems like you might own Photo Mechanic Plus. I'd probably recommend using Photo Mechanic Plus to search a catalog, as this would give you complete control over what images are indexed (and would only search the metadata that you chose to add to the images).
