No it doesn’t. It leans on Catholic dogma being defined by Catholics. Papal infallibility comes from Jesus’ promise to Peter that whoever leads the Church will always be guided by God. Since it comes directly from Jesus, the figurehead of Catholicism, the only “truth” that needs to be accepted is that Jesus + Pope (Peter) is Catholicism. There’s no question of truth or victory. The very foundation of the idea of Catholicism relies on the idea that the Pope is never wrong on issues of doctrine and dogma.
