Can't argue with that. And I don't disagree with Winogrand's comment that photographs are a particular type of picture.
But what you say applies to anything that tells a story (which is everything touched by the hand of man). Take someone's diary: that tells a true story, but a reader can only interpret it through their own experience of life - "I would argue that [a diary] can [create] an image that a person then tells the story drawn from personal experience not the [diary].
Nothing - no documentary, no book, no film, no photograph - can ever impart objective truth: all stories are "drawn from personal experience". The fact that some media - like photographs - are more shadowy and ambiguous in their story-telling than other forms of media - like literature - that can impart narrative more coherently is neither here nor there...
A photograph is a very complex cultural object, and dismissing it as essentially a pleasing pattern and confluence of form (however skilful their capture) does it an injustice. A photograph can be taken for all sorts of reasons - and "to see something the way it looks to a camera" is as good a reason as any (and better than some!). But once taken, it doesn't exist in a vacuum - it becomes connected to all kinds of meanings and stories: for example, it tells the story of the photographer (where and when they were at the time of the image, what they were doing, and often a lot more); it tells us about the subject (the people and the place depicted, and the time); it tells us about culture in the present (fashions, attitudes, cultural groups) and in the past (how things have changed - e.g. looking at a photograph of a smoke-filled bar while sitting in a cigarette-free pub tells the story of changing attitudes to tobacco)...
All these individual narratives knit together into an overarching story told by the photograph - a story inevitably different for each viewer (just as readers of a novel will experience its story differently).
Winogrand may have been disinterested - as are you - in the story-telling potential of a photograph, but it cannot be denied that photographs do indeed tell stories.
