Absolutely true, but assists are just one facet of the game, even greats like Nash in basketball or Pirlo in football whose passing was what made them famous, did everything else too. Imho being able to visualize the entire court/pitch etc and to create plays requires the highest level of mastery, it's absolutely amazing to watch and the few times I was able to pull something like that off, it's a better feeling than scoring. That being said, this doesn't translate well to the sex with a vibrator scenario because it's not quite a team game. It's an inanimate fucking object that your partner prefers to you. You're not Steve Nash opening the play for your team, you're the ball boy.
