There is a general consensus that “open-loop gain Aol” refers to the gain of the amplifier unit without a feedback network.
Therefore, the “closed-loop gain Acl” is, of course, dependent on Aol (but not vice versa).

In contrast to this, we define the loop gain (product of Aol and the feedback factor β), which is particularly important for stability studies.
