There's probably a lot of things I am not understanding, but the alleged story goes is that this guy invests $27 USD in 2009, and four years later the Bitcoin he had invested in became worth ~$886K USD. With the current value of bitcoin, it looks like that $27 is now worth over ~$18K USD.

Where did those figures come from for that story, and if it is true, what happened and why did his bitcoin investment become so valuable?
