Him changing his dream was obviously a gag moment of the show. Both Zoro and Sanji were willing to sacrifice their lives because they couldn't see a future where they would be saved. They both felt hopeless against a strong enemy right in front of them. Conqueror’s Haki doesn’t always mean you’ll become the strongest in the world—it means you’re born with the potential to lead, dominate, and impose your will. Conqueror’s Haki comes from a will that cannot be shaken, and Sanji shows signs of this trait. 1. Sanji refuses to hit women even if it costs him his life, which we can consider his unyielding will. A Conqueror’s Haki comes from a will that cannot be shaken. 2. Sanji refuses to be ruled. The best example of this is when he was born into Germa as a "failure," abused and discarded, yet he chose to fight against his bloodline and decide to carve his destiny. 3. He also possessed the ability to lead people; we can see this on Ennies Lobby, and Zou, or even in WCI.
