you can easily affect how your through pass is excecuted, when your target is starting to run towards opponents defense line, do the pass just before he run past the defender, if you use left foot to pass to the left side you will send the ball on the outside of the opponents defender, right foot to left side will pass it on the inside. One footed players with outside of the foot card will probably be more random.
Timing and posture affects the through pass.
