There's a lot of things you can say about Elon like crazy, blinded by money and power, hubris, etc. Lucky? If you start one billion dollar company, sure. The man built up Paypal, Space X and Tesla. The jury is still out on Boring Company but it's still drilling in Las Vegas.
I'm sure he got lucky with Paypal but you can't luck out this many times. The guy clearly knows how to build billion dollar businesses.
