Japanese is a very literal language. they would have said that. what was said is that

it was amazing that sasuke escaped itachi's Tsukoyomi and then was said it was likely only possible because they are brothers if it was that way it would have been a very literal Yes or No there is no doubt that had itachi wanted to defeat him in his prime he would have but itachi was weak from his illness shinobi can tell if a person is fighting to there full potential in fact black zetsu noted that something was wrong because itachi should have been making mince meat out of sasuke but never mentioned that he was toying with him or fighting weaker than his top potential

also at the same time itachi was trying to get sasuke to fight to the best of his ability to strengthen sasuke's Sharingan and make him a better shinobi. that would not have been possible if he was just letting him win.

Because like i said shinobi can tell if a person is not fighting to there full potential had itachi not been sick it would have been apparent to everyone present that itachi wasn't fighting to his full ability but his illness weakened him enough that a small amount of toying went unnoticed
