Hello @agmoore, it is always a pleasure to hear from you, I hope all is well at your end? So to your first question the answer is yes depth perception is not just innate our brain learn to perceive depth perception from clues and brain relies on this information as we grow which is why illusions are able to work on us. There are also conditions that may affect our depth perception these may not necessarily be pathologies but they all do a brain correlation. For instance, refractive errors, amblyopia and binocular Vision anomalies such as strabismus can cause one to have depth perception problems and this can be explained theoretically as the brain no been able to process the dissimilar stimuli been sent to it or it not been able to fuse dissimilar images. Pathological problems than affect depth perception are mostly neuropathic.
To your last question, some people may be considered to have better depth perception but in this instance too we can attribute it to their training or their line of work. Because these individuals have reprogrammed themselves such that they are better adjudicators go distance and depth. The same way a keyboardist after learning a practice developed his senses to learn easily pick up where each key is and can play with the eyes closed so does the pilot or sniper after their training is able to make better judgment of these distances required in their field.
I hope this helps, thanks once again for reading and I hope you have great week☺️
