Nah, Marco didn’t win that fight/ clash. He managed to successfully clash with her and not get blown away or got negged immediately but he sure didn’t win. We can see that their clash was more of their DF clashing with each other. Marco’s blue flames Vs Big Mom’s actual Fire Flame (Prometheus). And somehow blue flame was countering the fire flame. The moment things went to the hand to hand combat, Big Mom grabber Marco by his neck while Marco could do nothing but fear of what is to come. I’m not downplaying Marco here though. Dude fought against the 2 DF Teach and lived. He also managed to clash with all 3 admirals. He had to get nerfed in his fight against admirals for him to get actually hurt.
The reason why Big Mom asked Peros to finish him off is just to let Peros shine or have his moment. Peros has formed an alliance with Marco and Big Mom wanted it to end it all right there and then. She might have feared on Peros going behind her back and scheming against her. She was showing Peros the way it is done. Big Mom didn’t run away or postponed, she just had better things to do. Why would she waste her time on Marco who had nothing to do with this war. She only clashed with him cause he was standing in her way. And as soon as he was out of it, she went back to join the war.
It would be a whole different discussion if her and Marco met at Onigashima war and she still chooses to avoid him.
