"we're remembering.That's where we'll win out in the long run".What does that mean?

Much of Fahrenheit 451 focuses on Montag's desire to remember the past, in a world where people are no longer interested in memories. This quote directly refers to those men who've been living (hiding) outside of society, and the fact that they've made it their mission to commit lost (burned) books to memory. What the above quote means, is that no matter what happens to society, no matter what else is destroyed, words (books) have been collectively filed in the memories of living people. These words will be passed down, and ultimately, the erasure (burning) of written word has failed to destroy its message.
