Do disabled athletes have access to the same financial opportunities that able bodied athletes do?

Is that in any way relevant to the discussion of whether men should compete in women's sports when they will have an unfair advantage?

If a trans woman is better at sports than a vid woman

First off, you're using a misnomer: "trans woman". "Trans" is being used as an adjective to modify "woman", when "trans women" are really men who say they are women, and may or may not take steps towards looking like a woman. There are biological differences between men and women, which is why they have different categories in sports.

it's okay for disabled people to be put in separate leagues with fewer opportunitirs,

I'm not gonna lie, I laughed out loud when I read "opportunitirs". Yes, it's okay for disabled people to be put in separate leagues because they'd lose every time if they played with able-bodied people. They need their own leagues because they need to compete on the same level as their competitors instead of at a disadvantage. Can you imagine a wheelchair-bound boxer in the ring with an able-bodied one?

even if that's biologically unfair.

What is? Disabled people having their own sports leagues? Or not? You are making no sense.
