It's like everyone keeps ignoring the obvious.
Yes, bigger pockets will allow the weaker player to make shots/run out more often.
But it will do the same for the better players.
Your theory seems to be suggesting that the stronger team will ALWAYS beat the weaker team under any conditions, because they will always outperform them theoretically. But that's not the case.
I've explained how the bigger pockets can help the weaker team win a short race. They need some luck to enter into the equation so that when mistakes or bad fortune happen to the stronger team (scratches or ending up safe) the weaker team has an easier time of running out with bigger pockets when they obtain control of the table.
For a weaker team to win under any conditions, they will need enough games to come up where the stronger team has zero opportunity to run out due to misfortune or mistakes. Tighter pockets might not allow the weaker team to capitalize in these situations and win those games. So bigger pockets will help the weaker team capitalize in situations and games where the stronger team had no chance to run out at all.
