[Star Wars Legends] What was the point of the chosen one prophecy?

In legends, even though Anakin killed Palpatine on the second Death Star, he only truly died during the events of Dark Empire. The Sith would also still be around for at least 100 more years. Considering this, what was the point of the prophecy when the Sith still exist and Palpatine only died years later and not due to Anakin.

The imbalance came about because, through Palpatine's machinations, the Dark side had grown incredibly powerful, blinding the Jedi and other servants of the Light to his intentions, and even some of his actions. The Light was crippled by bureaucracy, negligence, tradition, politics, and a slew of other things. The Dark side had no such impediments: the Chancellor (or Emperor) made the rules.

The (first) death of the Emperor by Anakin's hand brought balance to the Force. It put a stop to the Sith, at least in that one moment. The Emperor was dead, Anakin turned back towards the light, and all that was left of the Sith were a few scattered apprentices.

When Luke put together the new Jedi Order, that allowed the Light side to grow and dominate, and thus they were able to fight the Sith on almost equal footing. Yes, the Imperial remnant fought on, and yes, Palpatine kept playing the part of the mole in a game of whack-a-mole, but the Jedi weren't as blind anymore. They didn't have to hide. At times, they even had the entire Republic behind them. Knowledge and training in the Force was allowed to grow and diversify.

It wasn't a perfect balance, but it was better than the utter oppression of the Force that existed under Palpatine's rule.
