I think he/she was saying that as an example of a way that "most people" rationalize things. It follows this sentence:
"When you combine all those things and still fail, most people will blame something besides just luck. [...]"
"When you combine all those things and still fail, most people will blame something besides just luck. [...]"
Or maybe s/he had a better idea than you had? Doesn't look like luck to me.
