This is an incorrect summary of the placebo effect. The placebo effect does require the patient to either believe it is effective, or at least not knowing clearly it is ineffective.
This is why clinical studies don't tell neither group (neither the treated group nor the control group) who is in which group, to not spoil the results.
And also, this is why homeopathy puts so much effort into spreading the belief they are effective despite all odds, up to the point of trying to convince people to abandon basic scientific principles.

Also, contrast this with psychotherapy, which usually does work even better if the patient understands how it works, because it enables them to become an active and more effective part of the therapy.
