What Chuck said (except I know nothing of Nikon and Canon - do they make
cameras too?).
We both did not mention designed service life of the shutter, which I guess
(*wildly* guess) might be 50,000 actuations in a triple digit body, but
150,000 in a single digit body.

I don't know that you'd find an official description anywhere but I think
it's fairly clear that, just like Canon, single digit bodies are
professional or pro-sumer grade, double digit bodies are pro-sumer grade and
triple digit bodies are consumer grade. Nikon had seemingly been following
a similar numbering system but has recently announced bodies with model
numbers that don't seem to fit the pattern.
But I don't think the model numbering system has anything to do with image
quality. Rather, it's build quality and features. An inexpensive body
(like the E-300) might have a mirror arrangement instead of a pentaprism. A
more expensive body might have a pentaprism but it might be small. A pro
body might have a much larger pentaprism and better viewfinder optics giving
a larger and brighter view. A consumer body is likely reinforced plastic
whereas the pro body probably has a lightweight metal alloy subframe with
plastic coatings or cover panels.
Other differences can be found in the electronics. A consumer body might
have a image single processor. A pro body might have 4 processors each
handling different parts of the image in parallel for faster shooting
speeds. Finally, image quality will change with the technology and not so
much the model numbering scheme. I've never done the comparison but I
suspect an E-620 (5 years later) produces a better and less noisy image than
an E-1. But you can probably take an E-1 into the Kalahari desert and
expect it to survive the trip.
