Being White in American society (possibly European society as well because they’re douchebags too) means that you know that people that look like you run society. If something goes wrong in your life then (barring unique circumstances like being from Appalachia or something) you can take solace in the fact that you’re White and just integrate yourself into a high social or economic class by befriending (or marrying) another White person better off than you. You have the benefit of living in a world superpower where the default rules of the society were set up by people in similar social locations to benefit people like you. This is not by any means to say that all White people actively participate in the privilege, because they don’t. However all White people do all participate. Simply put, American society is easier for those (of all colors) who have lighter/fairer skin.
