They got rich by either buying a few bitcoins in the first days or by mining bitcoins in the first days. People use their computer to mine "blocks", the blocks are finite and for mining a block you get a reward in the form of 25 bitcoins(atm 16,210$). This reward is split in half every four years. Because mining on your own takes a lot of time people mine together in pools of multiple miners and the reward is split between them.

As for the people getting rich by it; in February 2011 one Bitcoin equaled 1 USD, right now it's around 647 USD. Imagine you had bought 50 bitcoins by 2011, you have a profit of 32,300$ by now..
