sports are the easiest way to illustrate this point, but it also applies to other areas.
with coin flipping, replacing alice with bob does not influence the outcome. everyone has the same odds because luck is the only determinant. no amount of practice matters. the odds alice can flip 10 consecutive heads on her next turn will always be the same as bob's.
with basketball, replacing alice with steph curry vastly increases the odds of hitting 10 consecutive free throws. most importantly, alice can improve her odds with practice.
business is like poker: the longer the timeline, the more true skill emerges and dictates success. but if you only play one hand, then yes, luck may dictate the winner.
