Extract skills from seeded skills library

Hi,

Our client wants to enable dynamic skills V2 and delete some of the irrelevant skills from the seeded skill library.

How can we export all the available seeded skills? As per oracle's documentation the number of seeded skills are 11,656. I see the same number in the item catalog page as well. But when I export the skills from item catalog page, the number of skills which got exported are 10,000.

When I export all the skills by creating a BI report I see the number of skills as 13074.

Which of these numbers are correct? and How to extract all the skills(11,656) as mentioned by oracle in oracle documentation?
