As a prerequisite to ML, no one could stress too much about how important statistics are.
Diff between probability and statistics: Probability deals with predicting the likelihood of future events, while statistics involves the analysis of the frequency of past events. Probability is primarily a theoretical branch of mathematics, which studies the consequences of mathematical definitions. Statistics is primarily an applied branch of mathematics, which try to make sense of observations in the real world
Some interesting fact
