Natively Windows doesn't come with ssh no, but last I used it Git For Windows bundles a bunch of MinGW components, including ssh, which it calls out to.
Yep, I'm using that ssh too, it's really nice to have native ssh in Windows.
Git for Windows also ships with ssh-pageant that can use Pageant as key agent. Really useful if someone is using smartcard certificates (PIV, not GPG based).
