I agree with that, but it isn't what I meant, which was that there is no
such thing as a "ray" consisting of a stream of photons, because no two
photons will be in exactly the same path. I suppose you could create
some definition of ray that included a non-zero width (radius), and the
resulting finite volume could be seen as containing a stream of photons.
But I can't think of any particularly useful reason for doing that.

My sense was that the OP was viewing a ray as if it were some sort of
physical entity.
