“I take it as a given that a lefty pitcher can have success at the game with a lower velo than a righty”
Not true, deception at any same velocity and pitch characteristics will cause success or failure depending on witch side batter you face.
There are more righty batters making it easier to bat against lefties.
Lefties are coveted because they are 9 to 1 in the human population.

LoL, of course it is! In the southern hemisphere the righties ball tails naturally more than the lefties because of fluid flow dynamics, Bernoulli’s effect. Maybe? Maybe not!
