You'll be ok for the World Cup, the games will be televised. It is the exhibition games that are coming up that won't be televised, unless you have satelite.
Friendlies just means exhibition games. You are right Colombia is not in it, but they still play exhibition games, just to help other teams that are in it to prepare for the world cup, and also just for their team to try new players, new systems, and to work and things for their own improvement.
