This implies that all work is equal. If two entrepreneurs both work 80-hours weeks and only one is successful, I don't chalk up his success to luck, I ask what did he do during those 80-hours that the other entrepreneur did not.
if 100 people do random things, and 99 fail while 1 succeeds through sheer luck, do you repeat the same random things they did?
Survivor bias is a huge problem in learning from case studies. A particular tactic may work well through a particular combination of market, environment, team and timing. That doesn't mean it's a good tactic for your particular situation.
You absolutely have to study and learn from the failures as well as the successes.
