Same in finance, but there are still people making billions in statistically significant ways. Humans are complicated and unpredictable. Any field with 99% noise 1% signal requires different methodologies compared to, say, physics and computer vision ML. But you can still make some inferences and predictions (which, even if 100% "correct" will still only predict the 1% of signal, not the 99% of noise).
