Definitely not. You can win at bullet just by moving faster than your opponent so it isn't an indicator at all. Hence all the 2300 bullet players who would be defeated every time by a 1600 otb player at normal time controls. That's 1600 FIDE of course.
I know a 2850 bullet player who is 1600 blitz and probably like under 1000 uscf
That's quite rare. Most advanced bullet players at least have some experiences on other time controls. For example, I know someone with 2800 bullet in chess.com, but 2400 in blitz and rapid. The difference isn't that high that goes to 1000. As for the FIDE, he was 1900. Though someone who is 2850 bullet player and under 1000 USCF is completely rare.
