Parametric determinism means that some things in life happen because of certain conditions, or parameters. It is like a game of chess: in order to win, you must know the rules of the game and use them to set up the pieces in the right way. This way, the end result of the game is determined by how well you understand the rules. In life, some outcomes and decisions can depend on what specific conditions were in place beforehand, like the amount of money you have, the place you live in, or your family background. Understanding these parameters can help you make better decisions and plan for a better future.
