DL models are also the best way to predict the behavior of three-body systems in physics. Would you say DL models tell us something about physics?

You're talking about the output of a deep network predicting the solution to a problem it was trained on. They're talking about something completely different: the properties of the whole network (opening up the "black box") correlating with/predicting properties of brain regions while they perform similar tasks.
