I'm not consistent enough to be a good photographer, no matter how good the photos come out.

I agree that consistency is the key for judging if you're a 'good' photographer.
And it depends on how you judge consistency. For example, a professional portrait photographer is expected to produce images of a certain quality in each session. If you're doing seniors/college portraiture, that's a snap (pun intended) once you've got the formula down. The same goes for still life, product photography, anything where you get to control the variables and have narrow parameters for quality
For scenes with more variables like street photography, event photography and the like, a keeper rate of 10% is considered good. Can you make one satisfactory image out of ten taken?
The more you control the variables or understand the scene, the easier it is to develop a formula or best practice, and so your keeper rate goes up.
As for me, I'm good at some types of photography and not so good at others. I don't really do staged pictures and find myself foundering when called upon to do so. But I can get some decent keepers when I'm able to freewheel and shoot at events and in action scenarios like sports like boxing.
I'm decent at landscapes, streetscapes and travel photography, and I enjoy casual/candid family and friends photography. I could be way better and more educated about the use of lights and reflectors for portrait and product photography, not to mention how to pose people, etc.
