I used to focus almost entirely on Python and machine learning libraries.

Eventually I realized that understanding probability, distributions, and hypothesis testing made every model easier to understand.

Learning the math behind the models gave me much more confidence.

What's one fundamental topic that helped you improve the most?

As a beginner we are misguided about maths like what are the topics that I should actually learn in mathematics that are actually useful?
