The pool of students reviewed during ED is smaller, therefore chances are a bit higher. It also shows upfront commitment to the school, what all colleges would appreciate. However, you should carefully consider the binding aspect and financial implications of ED.
I think that you have a fair chance at NYU if you can show all your many achievements effectively. I have spoken to admissions officers and what they mostly look for is leadership experiences and if you can basically hold your own. ED definitely helps since it shows them your full commitment towards them - which is something that can bump up your chances. However, I would say to definitely consider what ED actually means since in the case that you are offered admission, you will be required to withdraw from all the other schools you’ve applied to and attend NYU.
A great part of your application is also your essay, so definitely put in a lot of work on that!
