Okay, thanks for all the responses people. Here's another example:
(we'll look at it from varying points of view)
You're playing a "C" player and he slams the rock into the 2 ball causing it to go 3 rails into the corner pocket.
Was he lucky? No, once again, the 2ball being pocketed is merely the effect of the cause, which was causing the cueball to contact the 2ball.
Now what if the tracking of the table were off a little, and the ball missed? Were you lucky? Of course not, your opponent just didn't know the tracking of the table was off.
