Doesn't matter if you're the best fighter pilot in the world, if Joe Average squadron pilot has the better hardware your ass is going to be whupped.
Bollox! I've defeated more advanced radars, missile systems and super-duper aerodynamics than I could count and certainly came out on top after a career flying, for the majority, a 25 ft span, high loading wing with a poxy monopulse radar. Guile, cunning, experience and initiative will overcome Joe Average, even if he has got every toy in the box.
