There are many, many life lessons I have drawn from my youth spent playing poker semi-professionally. Perhaps the most consistently useful one was that, as mentioned in the article, one's performance should not be assessed purely on the outcome.
In poker, you can play perfectly and still lose. That is true in almost every field of life. Or, to give it more nuance, you can play exceptionally well and only win a little, whereas someone has had greater luck can play relatively poorly and win a lot.
