When I am logging in my droplet for the first time using password, I see the following :
The authenticity of host '138.197.19.221 (138.197.19.221)' can't be established.
ECDSA key fingerprint is SHA256:qwR9naUT7NA6RrLSnu9RQ/jR1fJ2K5eakv52ONEyuOE.
Are you sure you want to continue connecting (yes/no)?
My understanding is that I can find the same fingerprint for my droplet at the digitalocean website, and if they matches I am connecting to the right droplet.
Is my understanding correct? If yes, then where do I find the fingerprint of my droplet at the digital ocean website?

It’s pretty simple, as long as you can get console access:
ssh-keygen -l -E md5 -f /etc/ssh/ssh_host_rsa_key.pub

This is the simplest fix I could think about using already existing concepts
You can find your SSH Key fingerprints in the DigitalOcean Control Panel. Simply login and click on the avatar icon in the top right corner (there’s a dropdown arrow next to it). From there, click on Settings and then from the left side menu, click on Security.
