Can large companies with millions of servers and VMs (like Microsoft Facebook Google or Amazon) run out of private ip addresses?

The 10.0.0.0/24 address space has 16777216 ip addresses available. Azure says it has nearly 4M servers, and who know how many VMs are there. Same goes for Google and Facebook.

And the 192.168.0.0/16 has a little more than 65k addresses, which can be easily used up by these companies, quite possibly in a single region.
