I am a serious poker player, I play slots on occasion, I’ve been known to play B&M bingo on now n then.. I buy a lotto ticket every so often, when I feel like wasting a buck.. and I bet on just about anything I belive I have a decent chance of winning..
Noone has studied me, noone has asked if I have a problem.. therefore.. noone knows if I have an addiction, a problem, a hobby, or a an ambition, therefor.. the stats are wrong. 
Which is basically my opinion on every statistic offered.. However.. if you want a more serious answer.. Who was polled? What class of people? What type of gambler? etc… More statistics are made up then are scientific.. or so I’ve heard was statistically proven.. and if you’re asking the correct group, you can definitely come up with an answer that suits you..
