The Gamora of the Avengers' timeline doesn't come back with Bruce's snap because her death occurred outside of the gauntlet's power. But the Gamora from 2014 turns against Thanos and helps Nebula escape his clutches before she disappears after the battle. It seems like she sparked a fire in Star-lord because he's shown searching for any sign of her while on the Benatar with the other Guardians of the Galaxy at the end of the film.
