Your statements are quoted:

>>>Black cannot overcome this [White's "significant advantage with the first move], in fact Black cannot even equalize.

If Black cannot equalize, how can Black score 45% of the time?

Here is a game where Black played the Center Counter game, known to be better
for White (White has historically scored around 58%), in which Black won (and
therefore disproving your statement that if White plays an "Opening by ECO
Classification that [is] better for White" then White will win. Note that person
playing White was World Champion Anatoly Karpov and had an 85 ELO advantage,
which should have increased his chance of scoring by about 11%.

And here is a game where White played the Polish Opening, known to be better for
