"Correlation does not mean causation" has nothing to do with the amount that correlation is the result of causation. It means that the former does not directly imply the latter, you need to add more to your argument than just the correlation argument. There could be other factors at play that were the actual cause of the change. These factors could be the underlying causes for both events, or the events may be completely separate.
The only thing you said was "because X and Y happened at the same time, they seem to be connected". You did not make any other arguments about how X could cause Y. Within the past hour, I went to the bathroom, and also at least one person on earth died. As you can see, to say my bathroom trip caused that persons death is illogical without any other facts or evidence to back it up.
