Humans don’t really use stereopsis beyond the reach of their arms (which makes sense if you think about it). Beyond that we use semantic cues, which is why we can also understand pictures.
Sadly most research in this area went out of fashion 30+ years ago.

This is outright false. A person with acute vision can perceive stereopsis out to 1/4 mile. Trivially, 3D movies are projected onto screens which are 10m away.

But of course we do. It's how we throw rocks and hit what we aim at. It's how we catch things. It's how we walk around anywhere that has obstacles. We use it beyond the reach of our arms really frequently.
