Is there any difference between critical path and longest path in DAG?

Is there any difference between critical path and longest path in DAG?

In every book I looked, they say that critical and longest path are the
same. The problem is that, on critical path all activities has to be a
critical ones. If I was searching for longest path, I wouldn't be paying
any attention on whether activities are or aren't critical. Or I don't get
something?
