You are not alone.I am playing here since early 2014 and I never hit the 200 dollar prize ever,also I never hit the weekly lottery also while having a good decent number of tickets most of the time and some weeks I intentionally have not used all the WoF spins in order to have a smaller number of tickets as supposedly you have more chances by having less tickets and still never got it.
I thought like you in the beginning but people more knowledgeable than me pointed out that usually there are more people with less tickets than few ones with a lot of them and as such from a pool of over 50 million users chances are higher than one of those people with less tickets to be a winner.
Luckily though this very week the first prize of the weekly lottery was won by a guy with 231 million tickets which got 0.34 Bitcoin and the amount you need to buy the 231 million is 0.231 but maybe he got them because he wagered a lot and refs of him wagered a lot too,point is I am always happy when someone with a lot of number of tickets wins the lottery.
