Some of these people - plenty of people - using those experiences, produce content that is particularly in tune with the zeitgeist of entertainment of their time. But this doesn't make them automatically successful, it simply means they have enough metaphorical funds to buy a lottery ticket to success. For every successful, talented person, there are likely 99 people with the same or greater talent who never got their 'big break' and had to change career paths or just do it as a hobby.
Yuki Kajiura has no formal education with music - she was a systems programmer - and Kevin Penkin is doing a Masters in the Royal College of Music. Yet in the end the music they produce is all used by the same anime industry, and a casual listener would not differentiate much between them. There are many paths to 'constant' success.
Add on the fact that once you have some success you have name recognition and clout, and that is enough to put you together with other similarly successful people who want to work with you. Even if you were not especially talented, these people can make up for your deficiencies and it is in a lot of people's vested interests to make sure you improve.
