“correlation does not imply causation”

I’ve seen this referenced a lot, especially with psychology, but can someone explain what exactly it means? How does correlation not imply causation? Sometimes, does correlation ever imply causation?

John and Mike are walking down the street. Mike falls into a hole. This happens every day for a year. The correlation is that John was with Mike every time Mike falls in a hole.

Saying “Mike shouldn’t walk with John anymore, every time he does he falls in a hole” requires more evidence than is provided. The cause of Mike falling in the hole is not demonstrated. It could be that John pushes Mike, or it could be that Mike is blind and can’t see the warning sign in front of the hole.
