True, but there’s a big difference between a certain amount of maths” which generally involves handling equations and the kind of “ proof from first principles” maths that develops those equations. The maths required by many STEM subjects is really arithmetic, statistics and a bit of basic algebra and calculus.It's a very minor point but this isn't quite true. Chemistry is the essential course for med school, although almost all applicants have Biology and most have either Physics or Maths.
Slightly more on topic, medical courses have a pretty heavy maths element that's above GCSE level. It's not impossible but it is a challenge for some. It's pretty hard to escape doing a certain amount of maths if you go into any STEM career field.
