That is true, but unfortunately it is not implemented very well for other purposes; most of the stuff relating to accessibility tends to be made for blind users. While it is possible to help blind users, good accessibility would be able to help everyone, whether you can see perfectly fine or not. "ARIA view" with a user specified CSS and using a combination of HTML and ARIA roles to decide how to display, can be helpful, perhaps. (This would be true for form fields too; some web pages implement their own, but sometimes specify by ARIA codes, what they represent; you can use that to replace them by the standard widgets instead of their specialized ones.)
