How much math do I genuinely need for backend/web dev? The takes online completely contradict each other.

Half the internet says 'you barely use math, it's mostly plumbing and logic.' The other half says 'you need discrete math and it'll bite you eventually.' I'm building web and backend stuff, not ML or graphics.

For those actually working in the field — day to day, how much real math shows up? I'm decent but not a math person, and I don't want to either waste months on calculus I'll never touch or skip something that blocks me later. Where's the honest middle?
