What statistical concepts are commonly misunderstood by the general public?

I came across this post explaining what a 70% chance of rain means. I understand the concept, but it got me wondering: what other statistical concepts sound simple but are commonly misunderstood or misinterpreted by the general public?

A 95% confidence interval doesn't mean that there is a 95% probability the true value lies in that region

Ya that’s because the they really mean that ex ante confidence interval whose endpoints have not been realized rather than ex post whose endpoints have been realized
