Sigh
Let's go through your list honestly.
Track & field: America produces the most athletes across the most events thats funding, not "more talented" — but Jamaica has owned the short sprints (Bolt and Shelly-Ann plus Elaine), and Kenya, Ethiopia and Morocco own everything from 800m up. Michael Johnson owned the 400, but that's one man in two events, not a takeover of the sport.
Biles: yes, genuinely the most dominant of the modern era. No argument.
Tennis: no. Steffi Graf is the most dominant player of the open era. 377 weeks at No.1 and the only Golden Slam in history, highest win percentage and most tour titles won. Venus doesn't belong in the conversation, and on the men's side, Black Americans have won zero majors in the 50 years since Arthur Ashe, while Djokovic, Nadal and Federer speak for themselves.
Basketball: Is an American sportn sport that isn't close to being as globally played as you think
Speed skating: Erin Jackson won one medal at a Games where the Netherlands won 17. That's not dominance.
Golf: Yes, he dominated his era.
So thats 3 people?

Americans are not more special/talented than the rest of the world; it's simply that
