I guess there's no way to verify this. Having driven for Uber and Favor though I find that to be extremely unlikely. Unless he is working part time and he only works on Friday, Saturday, and Sunday. Also if you are somewhere other than the US they probably have different labor laws and they might make more. I live in one of the 10 largest cities in the US and after vehicle maintenance and gas I probably made about 8-9$ an hour and I only worked at night.
Also, with Uber, most people don't tip, so people claiming that that's where the majority of the money comes from are just wrong - about 90% of your income is going to be from the fares. I've had times where I worked at nonpeak hours and made about 6$ an hour before expenses, so if you aren't working at peak hours it's absolutely brutal.
