Do I need to be good at maths to make nice games with a nice performance?

if I went back to the past in a tardis I would learn mathematics, that’s for sure.

But on the other hand, I have several prototypes made, a game in steam and I’m finishing another one. And I have no idea of mathematics beyond the very basic.

Between following tutorials and the number of nodes / functions that already do mathematical functions, there is no problem.
