And that posts some advantages we still need to do a lot of work on. Mammals and birds are able to learn online from a few examples per instance, shift to changes in underlying distributions relatively quickly and do so unsupervised.
This is the right perspective. It seems the OP believes actual photographs are privileged in some way. In reality, any visual input from our eyes counts as training data, as you said.
You seem to forget that the photos are labelled, which counts as supervised learning. What us humans excel at is unsupervised learning, which is difficult for machines. But yes, I agree that humans have the advantage of continuous video access.
