Again, you fail to see the forest for the trees.
Nobody ever wants to blame their OWN mistakes for why they lost, they want it to be someone/something else's fault. Luck is just one of those excuses.
What about the balls you missed? Bad safties? Missed kicks? Those are why you lost, not luck... If you take care of business AND DON'T GIVE THEM A CHANCE TO GET LUCKY, then luck won't affect the outcome of the game.
You can place the blame on "luck" as to why you lost a set, but you are only fooling yourself.
Now it's about players not being able to blame themselves for their mistakes?
Luck is a part of 9ball at all levels, and it SHOULDN'T be.
It's that simple.
Until the majority of luck is eliminated, 9ball will always be a garbage game.
