@Goyal99Raj that only applies to quantum scale phenomena. For macroscopic phenomena, adequate determinacy still holds true. So while determinism isn’t perfectly accurate, it essentially is.
@Abdibsz For localized, small-time phenomena, determinism is (mostly) correct. However, given enough time or space (distance) will affect macroscopic events -- i.e. determinism can't be extended to predicting far-off events seamlessly. https://physicstoday.scitation.org/do/10.1063/PT.5.026775/full/ provides a useful example of macroscopic uncertainty due to quantum events, and there's more comprehensive studies available about the interaction between quantum and macroscopic fields.
