At midterm, I am currently failing statistics (I genuinely do not understand a thing after asking for help repeatedly and using external sources)
Part of me finds this hilarious because I am a solid A student, but I am starting to panic because I need to pass. I refuse to take statistics again

I can relate to the struggle, because I also was usually a straight A student, or an even mix of A's and B's at worst. I also did poorly in math and math related subjects too, even with help. I don't blame you, I'd refuse to take more math than I absolutely had to too. I wish I had some concrete advice, but I don't really have a lot of that, because I haven't gotten a lot better at math classes, just no longer needed to take them. It's good that you're going to tutoring and trying to get help. There is a light at the end of the tunnel, you won't need to take any more math classes one day.
Actually, I do have one piece of advice: try teaching what you're learning to someone else. If that isn't an option or you don't want to do that, make a sideshow that recaps what you're learning in class and share it with your classmates (this has the bonus of helping your classmates too and not just yourself). They say the best way to learn something is to try to teach it. This also helps you pinpoint the exact thing you don't understand (it'll be the parts you struggle with the most when explaining them to other people), so you know exactly what to learn and it feels less daunting than trying to relearn everything taught in the class.
