Loosing weight to get pregnant

Hi I have PCOS and while I know you can have PCOS at any weight I am obese and I am curious as to whether loosing weight will realistically make much difference to me being able to conceive. I know overall it will make me healthier etc but if, in an ideal world, I lost a ton of weight but still had PCOS then I would still have the same TTC issues wouldn’t I?

I want to loose some weight so that is not an issue but I don’t want to pin my hopes on it being a cure all for my reason for not getting pregnant. Just wondering x
