I don't think it's the style of humour that decides if something is a sitcom or not.
It's probably the proportion of comedy to drama. Something like shameless has a dramatic storyline and plot elements etc. and throws some funny in now and then. Him and Her, while not having a blatantly 'comedy' storyline was there to make gags and have funny things happen.
No doubt there's some sort of sliding scale between comedy and drama and various shows fall in various places on it. Perhaps your opinion on whether something is a drama, a comedy drama, a dramatic comedy or a full blown comedy depends on how funny you find the jokes used.
