Public IP addresses vs private (nmap)

So I’m a bit confused between the two. My understanding of the public ip being the unique identifier of a network across the internet, while the private ip is for all devices on a local network.

Now when scanning the private ip 192.168.1/0.0-255 you see all devices connected on the local network so (nmap 192.168.1/0.0-255). Now when scanning for a public ip address you are only given the open ports(if any) and non of the hosts are displayed.

So my question, isn’t there an option to scan for hosts on a network similar to scanning your local ip where all hosts are displayed?
