This video started as a game. In "Guess Who", you can see how the Saints do not just come from one country, nor one lifestyle, nor one age group, social class, or way of life. A lot of them did not start out as Saints either, but were imperfect and sinners. The important thing is that they did not stay that way, but let God speak to them and help them to become the person they were made to be (or as Saints are often called in the Catholic world today, "the best version of yourself").
As the video says in the end, what will they be able to say about you?
