No, she doesn't.
48.2% win rate (should be lower because MF is her hard counter, but that's because MF is weak, not Vayne being too strong)
51.13% win rate (should be lower, but that's because Corki tends to fly off the handle with itemization changes).
51.58% win rate (again, ADC Varus is shit right now)
55.38% win rate (good, fuck Kalista, I hope she never gets played again)
49.39% win rate (makes sense, Draven is a high skill floor lane bully)
50.01% win rate (perfect)
51.64% win rate (makes sense, she hard counters Sivir)
50.67% win rate (makes sense, true damage>hybrid resistance passive)
52.96% win rate (insert racist joke here)
55.2% win rate (ADC Ezreal is a joke right now, should surprise no one)
51.13% win rate (that's a problem, but Caitlyn is very weak right now, so makes sense)
51.63% win rate (that's interesting, and probably the strongest argument to Vayne being as OP as the circlejerk says)
50.13% win rate (perfect)
The only thing that can be extrapolated from this data is that ADC Ezreal is shit right now, which is no surprise considering his AD ratios are godawful, Caitlyn is weak, which she is, Varus is weak as a designated ADC, which he is, and Miss Fortune is weak, which she is.
Anyways, don't let my facts get in the way of your circlejerk... CUE THE DOWNVOTES!
