[MCU] [Avengers: Infinity War] How did Dr. Strange surpass the Ancient One in using the Eye of Agamotto

In Dr. Strange, when the Ancient One uses the Eye of Agamotto/Time Stone, she stated that all of her predictions and probabilities led her to the moment before her death, then darkness. In Infinity War, however, Strange uses the Time Stone to peer into 10 Million timelines, in which he saw only one victory. How is it that Strange was able to see that one victory if he was unmade by Thanos' Gauntlet?

So you answered your own question here.

When the Ancient One used the stone, she was unable to find any solution or reality that did not result in her death. This was likely a result of her avoiding her death hundreds, if not thousands of times that she avoided her death using the stone. Eventually that usage put her into a position where she was unable to avoid dying. This is why no matter where she looked, she could only see up until her death, she couldn't find any reality in which she didn't die.

Dr. Strange does the same thing as she did, he looks at the future and see's the what he can see after that point. In the version where they win, he can still see past the point of his "death" because he is alive after that point. In all of the other versions, he probably couldn't see anything after the point of his death, but in this one single instance he could see events that happened after wards (because he was alive again).
