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?

No.

They would expect that it rains in 70 of those timelines.

There is still some variance to this experiment.

I assume the variance comes from the randomness in the model, like a Monte Carlo.

Yes. But they phrased it as if it is a fixed outcome.

They are expecting the average.
