^Red Harlow doesn't exist as a real person in the Redemption universe.

Yup.

Well red Harlow is mentioned by npcs and they describe him as a legendary gunslinger and is a playable character in rdr1 online and the npcs in rdr1 also speak about red Harlow so how isn’t he in the redemption universe

The most obvious thing is that when launching Red Dead Redemption, it was always noted that the game is a restart of the entire series in principle, so there can be no connection between them. Yes, and even if Red Dead Revolver and the Redemption Saga were one universe, instead of simple stories around the campfire, in RDR2 and RDR there would be a whole game chronicle dedicated to Red, since what Red did in Red Dead Revolver would not remain without a trace for not very long 14 years. All references to Red are exclusively Easter eggs left by the developers. Maximum we can assume that Red in the universe of redemption is a local legend or a story that is not related to the events of the game.
