The problem with this is that they made it as explicit as possible in the anime. It's not a blink and you miss it moment like in the manga, (which I'll get to) they spend a good chunk of time confirming that X Drake is indeed the 1% Percent Man.
The 1% Man plot died here as it was made to give Drake the motivation to ally with Luffy, which happens right after this scene.
Even in the manga it was heavily implied to be Drake. In the scene where Hawkins read his fortune, right before Drake got cornered, Drake said "1%? Sucks to be him."
Chapter 990:
He might as well have been winking to the audience when he said that.
Worse of all, even if there was someone else who has a 1% chance of surviving the raid it'd be completely pointless. A 1% chance on an ally, especially a main Straw Hat, might as well be 100%. Literally, no one in the community would take it seriously if it was the case.
Not to mention that this applies to Drake as well due to his relationship with Coby and SWORD.
The relevancy of the 1% man plot died the same chapter it was born in. It was a line made to set up a dramatic scene and nothing more.
