Modern dishwashers are effective. You don’t need to rinse the plates before starting the dishwasher. (But of course you should remove large food particles first.)

However, for a single-person household it might not be worth it. For a household of more than two it’s definitely worth it.

What's the difference between "remove large food particles" and "pre-wash"?

If I can't take the dish off the dinner table and stick it into the machine, it means I'm pre-washing in some sense.

It means take the fork and push stuff into the trash. This isn’t rocket science here.
