SpaceX can probably still be considered a startup its older, but rocket development is a longer timeline than say social media. I doubt that Spacex is profitable yet, it likely could be if it stopped development of new systems (starlink & starship).
That said the definition they are likely using is companies they expect to go public, but have not.
