If you interpret the term literally, then yes. However that's not the correct approach when dealing with terms of art like 'security through obscurity.'
Wikipedia describes the term as it's actually used (emphasis mine):
> Security through obscurity (or security by obscurity) is the reliance in security engineering on design or implementation secrecy as the main method of providing security to a system or component.
An properly configured sshd on a non-standard port is not in any remote way using obscurity as it's main method of security.
