Agreed, but some people (myself included) are fortunate to have a natural aptitude for skills that are highly valued. In my case, it led to a successful career as a software engineer. If, on the other hand, I had been born into a different world where (for example) art and musical ability were the most-valued skills, and STEM-related fields were not valued, I would have been screwed.
It is not just having the skills that are highly valued. It is also learning how to use these skills to properly fit into an environment where others will find you productive. I have seen many, many examples of this in my life.
Having a math and computer science background got me a summer internship program at Megacorp. However, how I used those skills to accomplish things, and relate to people, it was got me hired permanently and started my career.
The year I started full time at Megacorp, they hired another student from my school. He was also a math and computer science major. However, he was very full of himself. And did not, as a summer intern, hesitate to tell others that they did not know how to do their job because he was smarter and would be getting a degree from an Ivy League school. He would also do other socially inept/obnoxious things. I tried to console him a couple of times, but he would not listen. At the end of the internship, Megacorp did not offer him a job.
And it was not just Megacorp. A few years later, DW and I ordered a pizza for dinner... and guess who shows up as the delivery person? And it was not just a "side hustle"... even with a math and computer science background and skills from an Ivy League school, they could not overcome his social skills in believing everyone else was wrong and he was right... and he continued to wear out his welcome in many places. It was not until he was almost 40 that he figured out he was the problem, not everyone else.
Having natural aptitude for something is a good start. But you need to work on that aptitude and develop it in conjunction with other skills. There are many "natural" athletes who are surpassed by those willing to work hard and longer to improve their skills and to be prepared to take advantage of opportunities.
