For big companies such as banks this cost comparison is not as straight forward. They have whole data centres just sitting there for disaster recovery. They periodically do switchovers to test DR. All of this expense goes away when they migrate to cloud.

They need to replicate everything in multiple availability zones, which is going to be more expensive than replicating data centres.
They still need to test their cloud infrastracuture works.

Just to pay someone else enough money to provide the same service and make a profit while do it
Well corporations pay printers to do their printing because they don't want to be in the business of printing. It's the same with infrastructure, a lot of corporations simply don't want to be in the data centre business.
That's how nearly every aspect of every business works; would you you start a bakery by learning construction and building it yourself?
Construction is a one time cost. It infrastructure is in constant use.
It's like accounting and finance. Yeah a lot of companies use tax firms, but they all have finance and accounting in-house.
