How do people luck out into video game testing jobs?

honestly, i find more glitches and snags in games as a casual player of them. i always somewhat wondered how people managed to get these seemingly dream jobs of playing video games all day and making monetary gain. i was (mis)informed when i was a wee child that such jobs weren't in existence, and that only coding jobs were. further on this, i was informed that coding (in binary, mind you) was the only job available in gaming. at all. it was seemingly incorrect information. obviously, there are people out there that indeed test the games as their job. so i suppose my question is stated above, how do people get so lucky and find such a position? the almighty google seems to direct me to hoaxes, rightfully so, as it seems farfetched. but no harm in inquiring.
