Not true at all.

What that saying in reality is supposed to say is that you will only "find love" if you're not needy or pushy.

Just be.

Dont demand stuff, dont pour emotions over people you meet. Just be warm, fun and cool to be around, while clearly signalling that you hve no æroblwm with lack of interest.

Most relationship start like this (at least in western societies)

Fum/chemistry -> sex -> ??? -> more sex -> feelings, relationship and all that jazz

If you start pushing feelings or relationship talk from early on then it becomes all about you and your needs and not about the other person and that will lead to rejection.
