Why is it possible to get runner runner cards to win?

[soko]

Seriously. I am completly dumbfounded.

Perhaps it is my skills that don't allow me to grasp the concept of calling down with garbage

Are there people who exist, who feel, even at higher limit poker that calling down 2 random cards and hitting gutshot gutshot runner runner straight draws are worth shooting for?

Alright so I got bad beat by are few 1-33 shot drawouts, the post isn't asking for sympathy, I am serious interested

Do enough people exist in the world to call down with such grabage and hit such rare and unbelievable draws or do they just know what cards are going to come?
