She was talking about her mom. Whether or not she was a pirate I can't remember. But the "Big Mom is Lola's mother" thing is nothing more than speculation that for some reason a crap ton of people take as fact. She's not Lola's mom.
All Lola said is her mom was a famous pirate captain in the New World. Everyone instantly jumped on it being Big Mom for no reason.
After actually seeing Big Mom, I really doubt it's her.
