If you go for a walk on a rainy day you can step around as puddles as much as you like, but your shoes are probably going to get pretty wet. That’s just what happens. You can’t avoid it.
If you submit a PhD thesis you can proofread and edit for months beforehand, but your examiners will probably find something for you to correct. That’s just what happens. You can’t avoid it.
If your shoes get wet on a rainy day then there’s simple steps you can take afterwards to dry them.
It’s the same with corrections. You’re given a list. You know why your examiners are asking for the corrections: to help make your thesis the best it could be. Not perfect, but the best that anyone could reasonably expect. To complete them you make a plan, work carefully and get them done.
You should obviously work to submit the best thesis you can, but you can’t do much to avoid corrections.
