Comme par hasard (or the variant comme de par hasard – considered as faulty but still used, sometimes for a humorous effect) would rather fit as an ironical comment in situations where you suspect someone has a hidden agenda and you rather think there is no hasard (in the sens of coincidence).

-Je suis désolé, j’ai oublié mon portefeuille.

-Comme par hasard ! Et je suppose que je vais devoir payer alors ?

As in your example, if you want to express that an event or a situation is not surprising at all (without this sense of getting suspicious at an alleged coincidence), you can say:

Evidemment !

Ben tiens !

Voyez-vous ça ! (a bit old-fashioned)

Or on the tone of irony:

Quelle surprise !

Tu m’étonnes !

Sans blague ! (variants: sans rire / sans déconner / sans déc)
