I am totally out of the loop when it comes to these things. My client always opens in plain text or html render with JS and external content disabled.
I believe this is true for most clients. On the other hand security scanners, browsers engines and other Middleware stuff can trigger such a counter without any user interaction if I am not mistaken.

The pixel is just an image, so unless you disable email images loading by default, the server will still count you.
Pre-caching will sometimes mess with the counters though, making the counts lower than the actual.
I understand. The last 3 email clients I used do not load images by default (that what's included in external sources [previous comment]).
