I mean doubt all you want, doesn't change the fact that Oda has had Kid/Law fighting her for 12 chapters now and hasn't changed anything about it
If she wasn't meant to lose in a arc where she's been nearly as featured as Kaido, Oda would have made it clear she's not a signficant factor and removed her from the plot. She wouldnt have been on the cover of Volume 94 and Volume 99. Her son wouldn't have lost to the minks. She wouldn't have been tied to Kaido and Rocks.
It's extremely clear Oda has been setting up both Yonko to lose. Even CP-0 talks about both losing.
