No, it's not. The joke is that there is a correlation, but that actually correlation doesn't mean causation. But here we have a situation where there is neither correlation nor causation.

The problem is that the joke suggests that correlation is when A -> B (or at least it appears as such). Implication (in formal logic) is not the same as correlation.

Sorry to get mathematical..

P(A∣B)=P(A) iff

P(B∣A)=P(B) iff

P(A∩B)=P(A)P(B)

->𝐴 and 𝐵 are uncorrelated or independent.

There is no correlation with events with probability 1

isn't that just Bayesian apologist propaganda?

Don't even need to bring probability into this. Death is certain, and correlation requires variance.

Yup.

If the rate of dying is 100% for all humans.

Then the rate of dying for both humans who confuse correlation and causation and those who don’t is 100%. Hence there is no correlation between the confusion and dying. So no one is confusing correlation or causation, because neither are present.
