Yes, money maters.
Rich kids can conjure tens to hundreds of thousands of dollars from "friends and family" in a mater of days. Hours even, if they're really connected.
They can then pump all that money straight into advertisement, barely even need a working demo - just something that looks like a product. They can do this many times over.
If you're gonna bootstrap something with $0, then you need to win the algorithmic lottery, simple as that. And even if you have some life savings laying around, you only have one go at burning those - though most working class folks in their early 20s rarely have the substantial funds needed to promote a product.
