What is the ratio between public and private cloud data centers is in terms of server count / data center count etc?

I think the amount of enterprise DC's / colocation facilities is pretty stable but that almost all of the growth is in public cloud. Don't have any data to back this up though.

In terms of existing infra, private DC capacity is surely an order of magnitude more than public cloud. New capacity getting installed might be a bit more evenly split. How you differentiate between any private infra and private cloud I don't know.

Public clouds often use colo facilities, especially for new/small regions. So colo != private.

Depends on the public cloud probider, but the leading providers are actively building their own buildings for expansion purposes.

For example MSFT investing $15B in its datacenter infrastructure. https://azure.microsoft.com/en-us/overview/datacenters/.

GOOG naturally don't need to colo anything, they have their own https://www.google.com/about/datacenters/inside/.
