The individual sensor elements correspond (roughly) to pixels in the
image. It's actually a little more complicated than that, because with
most digital cameras each individual sensor captures only one color
channel of a pixel, and the other two color channels for that pixel are
made up by interpolation; but pared down to its simplest, you can think
of the individual sensor elements as corresponding to individual pixels.
That's closer to the truth than trying to think of them as grains in
conventional film, anyway.
The person who referred to a digital image as "grainy" probably ment
that the image appeared coarse, like one would expect with grainy film,
not realizing what the term "grainy" actually means.
