He more so explained his story, which was essentially: “I studied hard, got into a good school, and got a great job,” rather than explaining how he focuses on the process. The only example of “process” was his discovery during his internship that he _should_ focus on process.
But the story you're describing isn't accurate. His story is more like "I studied hard, did not do well, as a result my parents sent me to a good school in a different country, and got a great job".
If he had done better than he did in his Chinese High School, his parents may not have sent him to the UK, in which case he may not have been as successful. So it still aligns with the idea of the story that we really discount the value of luck in our successes.
