By your definition, every spam message is a mistake for the spam filter because it "reads" all of them (at least to the same extend as it "reads" any non-spam email). The filter is more accurate because it is fast enough to be more thorough than any human can possibly be expected to be. If we could thoroughly analyze hundreds of emails in a matter of seconds, we would have no need for spam filters. We have spam filters because we don't have the time (or the patience, for that matter) to be as careful as a filter.
