This list does not mean that there are 54 authors (if to assume that there were only 2 sons of Korah).

The correct number of authors of the Bible is definitely more than 60, and most likely more than 100.
We do not know the number of chroniclers who created the material and the scribes who compiled the texts.

Not only authors

There were also translators, co-authors, editors, publishers (scribes).
It was often a team effort.
