Luffy will defeat Katakuri. If he can't defeat Katakuri obviously he wouldn't be strong enough to fight Big Mom. You can't become The Pirate King by losing to another Pirate Captain's number 2. If he doesn't beat Katakuri here he would need to fight him again in the future and beat him. The next time the Straw Hats go up against the Big Mom pirates Luffy will need to focus on Big Mom so I imagine Sanji or Zoro would fight Katakuri. The only way Luffy won't defeat Katakuri here is if Sanji's cake pleases Big Mom enough to stop her from going after the Straw Hats for a while and she tells Katakuri to stop fighting.
