There's no binary here between ignoring luck and fatalism, and most people inherently realize that even though luck is a factor the best they can do is improve their average result rather than completely controlling things. The best people in any field will focus on what they can control and not worry about the rest.
To me the problem is that people generally want to explain luck away in hindsight: the team that won the game on a last-second shot won because they "wanted it more," the business that comes out on top "executed better," etc. It even comes into play in ethics, whereby the exact same action (say, driving drunk) often has different outcomes (hitting someone versus making it home safely) that cause us to judge people completely differently.
In other words, people hate the thought of luck determining things, and thus we over-ascribe outcomes to individual differences, overly glorifying the winners and shaming/demonizing the losers.
