So the reading on the ammeter isn't the true state of the wire? Might be oversimplified, but is that not too far off base?

Except that the principle is entirely limited to quantum mechanices. Further, the statement that the reading doesn't measure the "true state" is a little off. The theory holds that their is no "true state" (or in this case "true location") of a quantum particle.
