Don't use the 20% have completed a raid number kid you'll hurt yourself no more than 20% have even maxed out a single subclass on a single character type Less than 20% have got an exotic Something like 22% have gotten all legendary or better weapons equipped Which means a lot of people stopped playing either right before or after hitting lvl 20. If you look at the trophy stats on your console for other games you'll see that barely 20% ever beat any game other than wheel of fortune
