Many rays of light are emitted from a source, at many different angles. The further away you are from the source, the further apart the rays will have gotten, meaning fewer will be on a path that intersects your eye/camera. All of the light still exists, it’s just nowhere near you.
Over very, very large distances light does truly lose energy due to cosmological redshift.
