Exactly. It's a manifestation of selection bias. We pay attention to the Gateses, Zuckerbergs and such, and disregard the thousands and thousands who dropped out of college and ended up achieving nothing in their lives. It seems to me that Microsoft's or Google's successes are anomalies that one should not try to emulate...
The key is having a marketable skill. With a good education, you have both a skill, and a certificate saying you do.
Without an education, you might still have a marketable skill, but people have to take your word for it.
Personally, I don't have a university degree. I do have a marketable skillset, but it's up to me to prove it, and through a bit of luck I'm in a pretty good position. But it's certainly not a path I would recommend others to travel, you leave too much to chance.
