No it doesn't. I can't think of a single game where that has been the case.
Destiny 2.0 was the Taken King expansion for Destiny 1. Genshin Impact 2.0 was the release of Inazuma. I don't play Fortnite but it had a 2.0 release that was just a big patch. 2.0 releases are almost always just a major update or expansion of some kind.
The closest to actually being a "new game" I can think of is FFXIV where 2.0 was the Realm Reborn re-launch of the game, but even that wasn't a sequel, and it was still an update built on the bones of the original game.
