That’s not what “prove” means and notably is not specific to black which was the more significant claim.

I think it is highly likely that perfect play results in a tie for both sides.

That's what a draw is my guy.

Yes I’m agreeing with you. But I’m saying it’s not proven and it’s not expected to be favoring either side as claimed.

Saying black can at best tie against perfect play is not the same thing as saying both players can at best tie when facing perfect play.
