I see, you don't know what I'm talking about. My apologies, I assumed a common background. Here's some introductory materials on Bayesian vs frequentist interpretations of probability:

Bayesian and frequentist reasoning in plain English

https://stats.stackexchange.com/questions/22/bayesian-and-fr...

Comparison of frequentist and Bayesian inference

https://ocw.mit.edu/courses/18-05-introduction-to-probabilit...

To Be a Frequentist or Bayesian? Five Positions in a Spectrum

https://hdsr.mitpress.mit.edu/pub/axvcupj4/release/1

Beyond Bayesians and Frequentists - Computer Science

https://cs.stanford.edu/~jsteinhardt/stats-essay.pdf

You'll find that it's a big subject with a long history and many strongly-held opinions that have nevertheless evolved over the years. Happy reading!
