Is Astrology actually one giant placebo effect?

Correct, astrology is like a hypochondriac. It's all in the head lol. Its also a birth discrimination, bias, general, stereotypical, overrated, wrong, etc. Shall I go on? Don't listen to what people are feeding you, its a bunch of junk! Its completely general, which makes you think they are right. Experiment, test it out for yourself. Look at all the horoscopes and astrological signs without reading the actual sign. Doesn't it ALL sound so familiar? Simply, because it is. If you truly wish to understand life, read astronomy.
