It's not zero. I receive a few spam iMessages a year.
But it's definitely orders of magnitude below SMS/calls.

SMS and call spam are big annoyances but can also be dealt with. On my Android, the Google messaging app is really good at stopping them.
I doubt that Apple doesn't have the tech competency or the money to either build, license or acquire a really good spam filter. Heck, they can acquire every single spam filter company and start-up in the world and their money pile would barely dip.
