Keep in mind that the actuation count can be reset such as if a camera is sent to a shop for repair/refurbishing (e.g. replacing the shutter assembly).  Also, shutter counts are a rule of thumb.  I’ve seen 100,000 to 150,000 mentioned depending on the camera, but it’s dependent on the make and model and it’s an average life expectancy, not an absolute.  For more information on how to measure shutter actuations, see Finding Your Camera’s Current Shutter Actuations.
