I wonder then, if this is the case, what gives us the perception of depth?

Our depth perception is finely tuned to the two slightly different images that our eyes see. Especially with XR headsets that try to recreate a 3D environment with 2D images, we can see some interesting facts about how our eye works, like the fact that our depth perception is likely highly dependent on environment cues. There's an interesting paper here: https://ieeexplore.ieee.org/document/8985328

I was wondering the same thing! Did some quick research and it turns out that our ability to perceive depth is highly reliant on our "binocular vision", or the ability of our brains to put images from each of our eyes together. Because each eye is located at a slightly different position, the eyes relay images from slightly different angles and the brain is able to synthesize them to more accurately judge an object's distance. There are other factors that play a part in our depth perception, including monocular (one eye) cues like relative object size and motion that do not rely on binocular vision - but binocular vision plays a huge role, which is why people who are only able to see through one eye have a substantially decreased ability to gauge depth. (Try playing a sport with one eye closed to see how it affects you!)
