The average organization with 500 to 1,000 employees is running between 100 and 200 SaaS applications. A fraction of those are managed by IT. The rest were procured by individual departments, teams, and employees using corporate credit cards, expense reports, and in some cases personal cards that get reimbursed. The finance team knows about the ones with purchase orders. The IT team knows about the ones that went through the security review queue. Nobody knows about all of them.
