No la, the shutter count can mean a number of things, but usage is definitely reflected in his shutter count. If it is high it just means that he's been using it a lot, does not necessarily mean that it is abused.
So you can look at the condition. And if the shutter count is very very high, you might want to consider not buying the camera, or at least try to hack down the price, since it is possible that you will have to replace the shutter unit yourself after a while if it breaks down after you get it.
I didn't put up the seller's nick to shame her or whatever. I enjoy the conversation with her and am very happy with the transaction. Just want to put her nick up to let all fellow CSer have total confidant with her.
Shutter count alone might be used to guage the remaining lifespan of the camera, bundled with the actual camera age, it can tell you how old the electronics really are. Cameras that are a few years old with a low shutter count is relatively ok, if the cam has been stored in a cool drybox. If its many years old, and has a high shutter count, it means the previous owner has used it alot. This means the electronics are probably more worn out and hence the camera has a greater chance of breaking down anytime soon. Our high ambient temperatures, especially when the camera has been used alot outdoors, tend to destroy electronics faster than cooler temperate climates. Even if the circuit boards are fine, the sensor may have degraded in its performance. (ie less saturated colour, increased noise etc) Replacing the shutter is then very cheap compared to replacing the sensor.
Again, I must warn that such values are very relative and cannot be used as an absolute guage. Some cameras break down right out of the box, some break down after 3 rated shutter lifespans. Some cameras have their sensors go all crazy after a few years, some loose its day 1 qualities very very slowly.
