The term “causality” has a nice intuitive definition, but has eluded being well-defined for decades. Establishing causality is harder while there are many statistical tools available to establish correlation between events or actions. If A and B tend to be observed at the same time, you’re pointing out a correlation between A and B. You’re not implying A causes B or vice versa. Causality and correlation are often confused with each other by an eager public when a relationship between two events is claimed to be necessary (or inevitable) rather than occasional (or coincidental).
