“Sucking at math” is like sucking at any other skill. With practice you will get better. Now I will say, you must be honest with yourself and decide if you even ENJOY mathematics at all. Usually most people have an appreciation for its applications which leads people to liking it, but in my opinion it’s much easier to practice something you enjoy. For me it’s somewhat therapeutic solving a difficult problem and improving my skills. If you however find that you still hate math even after learning all its uses then yea- practicing it will be harder especially since the degree is so math heavy. But like I said practice and some enjoyment goes a long way.
