The Short Answer

this is a cultural thing and if you travel to various parts of the world you'll find the same does not hold true for them. for instance, Chinese and Japanese consider 4 to be unlucky and not 13. The reason for that specifically, is because some of the pronunciations of 4 are similar or the same as their word for death. 13 may be considered unlucky for many reasons but a common belief is because of the christian religions "last supper" where jesus and his 12 disciples ate… judas, the one that betrayed jesus, was the 13th person to sit at the table. 7 on the other hand may be a rule of 5s type thing… i.e. people looking for certain patterns will eventually see them in just about everything. I also suspect christian religion has something to do with it though… I've heard many times how 6 (specifically 666) is supposed to be the number of the devil and so 7 which is above six, would be the number of god.
