No, SSH requires a byte stream transport.
What you probably saw was a reserved port listing. In many cases, IANA has
reserved both UDP and TCP ports for the same service, just for
consistency. In some cases it's meaningful to run a service over either
UDP or TCP, but in most cases it doesn't make sense.
