Yes, but this use case is different. In general, correlation is not causation is true, but less true in this case of SEO. This is because all algorithms (even ML-based) are essentially all cause based (If this then that). Here the odds of a correlation existing because of causation is much much higher than other random correlations in nature. Besides, there are other mathematical models to prove causation where intervention may not be possible (see the book "The Book of Why" by Judea Pearl). We are not there yet in the field of SEO, but we are getting there. Not to mention there will always be people who simply refuse to learn. There will always be flat earthers. Cant help beyond a point.
