It's not a matter of belief, it's a matter of reality being changed by the positions of various planets in orbit around our sun, etc., which it's not, except as you note, subjectively.
I'm agreeing with you that lots of people believe astrology to be true, and thus act on it. To that extent, it is "true"in that it changes real world behavior. But it is only "true" the same way the placebo effect it makes it true that a medicine works.
