Like my dad always used to say.....
"A poor workman always blames his tools."
So yeah money helps that's why I buy the best I can afford at the start and if/when I don't win I never go "if only" about my gear. And I hope I made the right initial choices because I gotta live with them.
So lots of money = champion...No!
Lots of money spent on the right choices = yes IF you learn to live with them and make the most of what you got.
