Well, think of it this way. In a game or a virtual reality setting where avatars exist. 'Who lives' refers to which of those avatars manage to continue in the virtual world, perhaps due to certain skills or advantages. 'Who dies' is obvious, which ones meet their end. And 'who tells your story' might be about who has the narrative control. Is it the avatar itself? Or some external force? For example, in a role - playing game, the game developers can be seen as those who tell the story of the avatars through the game's plot and lore.
In social media, we can also apply this concept in a way. Our online personas (avatars in a sense) can have different 'lives'. Some might gain popularity and thrive (live), while others might fade away (die). And the users themselves, as well as the social media algorithms which decide what gets shown and how it's presented, are like those who tell the story of these online avatars. For instance, a person's Instagram profile is like their avatar. If they post interesting content regularly, their avatar 'lives' and their followers (and the algorithm) help tell their story. But if they stop posting or post uninteresting things, their avatar might 'die' in terms of losing followers and visibility.
Winston is the main character who experiences a form of death. After his time in Room 101, he no longer has the same will to resist. He gives up on his beliefs and becomes a tool of the Party. And we can assume that many people who were once rebels or had different ideas in that totalitarian society were killed off. The Party doesn't tolerate any opposition, so anyone who goes against them is likely to face death.
