Why doe muscle size does not necessarily correlate with muscle strength?

Question

As the title says. Why does hypertrophy (growing muscle tissue in size) does not correlate with the strength of the individuals training for strength (as in heavy weight lifting, without growing muscle tissue)?

Adding this because I didn’t see anyone else mention in.

There are two basic types of muscle fibers. One is short and fat, the other is long and thin.

The thin ones build up while doing anaerobic exercise.

If you have an overabundance of the thin muscle fibers you can be very, very strong without the same muscle thickness.

You see this in rock climbers in particular, who are extremely strong for their weight and muscle thickness, particularly in the arms.
