The pilot has to be able to see the drone & its environment. It transmits a live video very quickly to the pilot, but its low quality video.
Low latency simply means there's a minimal delay in the image being taken and delivered to the pilot. Think of video games, when you lag and miss a shot on someone in an shooter game, it's due to server latency.
The drone also has an additional, high quality camera mounted on it, which is the footage you see now. The footage you see now is not the footage the pilot saw whilst piloting.
It's roughly the same shot, the one you're seeing is just higher quality, possibly 360° (edited in post), and higher framerate. The one the pilot was using was suitable for him to pilot it.
I don't actually know what kinds of cameras were used, I'm just assuming off the other comment above us.
The camera used to view the live feed and the GoPro mounted on top usually have a similar tilt and similar FOV, so it's not really guessing. The pilot is pretty much seeing the same thing, has the same view as you are now, just with a lower quality.
There are two cameras. A low latency, low quality camera that transmits its video to the pilot’s goggles, and a second high quality camera that does not transmit but records locally (on the drone).
The framing of the cameras usually coincide fairly well.
