Let's think about this for a moment. After Bege's assassination plot failed, the best that Luffy's small group could do concerning Big Mom was run from her. The escape from Totto Land did not happen without cost. Pedro sacrificed his life, Bege lost his ship, and the Sun Pirates sacrificed their ship to save the Sunny. Also, the reason Luffy took the time to advance his Busoshoku Haki was because of how powerful Kaido is.

If Jinbe was a creature that cannot swim and breathe underwater, then I would be more worried about him. I do not recall the Big Mom Pirates using ships that can go underwater. If Jinbe was surrounded on land, then that would be a different story. Also, no matter how powerful they may be, Devil Fruit users have a weakness towards seawater, so of course Big Mom could not chase Jinbe under the sea. Let's not forget about the Germa Kingdom. I say they had the smaller chance of escaping. If Big Mom allowed the kingdom to get away while she had her senses, then that would make her truly incompetent.
