How do you people make so much in your 20s?

You all might obviously guess that I'm speaking about the other two posts in which each of them in their early 20s making 50+ LPA and 70+ LPA respectively. Honestly curious, how do these guys get paid so much? I feel like salaries in IT industry are heavily inflated. I'm from EEE background, trying so hard to find a job in Data field. I've previously worked in my field for 3 years, but the growth seemed pretty less in the long run, hence the switch. Finding a job as a fresher (in IT industry) is so hard man. I'm mainly looking for the startups. They either ask for experience, or the pay is very similar to what I made previously in my field. (which is <10 LPA). Above all, I'm not even getting responses from companies for my applications. So yeah, how do people in their 20s make so much in the IT industry? Is it only FAANGand big corps or applicable to startups as well (like unicorns etc)???
