In the lay meaning of the term "accurate", you're right. This thread is not about the lay meaning. In a lay sense, accuracy and precision are more or less synonyms.
When one is talking about scientific instruments, for example, accuracy and precision have very distinct meanings. With the technical meaning of "accurate", consistently hitting the outer ring is accurate if the mean is right on target. This kind of throwing is not very precise (technical meaning).
Two statisticians went duck hunting ...
I am well aware of the distinction between accuracy and precision. My point is that if all the darts hit the outer ring, the average turning out to be the center would be dumb luck.
