It's an american joke, my apologes for both using a cultural reference and making a pretty snarky comment.
A more "HN-spirited" comment would have been:
You aren't speaking from any real authority or
experience, and your 5 paragraphs could have been summed
up with the following: "when you gamble you don't expect
to win them all, so regret is baked into the equation".
Please be more concise with your comments and get to the
point.
There is a series of commercials where someone who is handling a task well explains that they are not a professional but they slept at a Holiday Inn Express the previous night.
The original commenter's post read like the beginning of one of these commercials.
