I think it's closer to 100%. I was bullied and didn't realize it. Later, I was bullied at work and thought I just had bad luck. The way to not get bullied is to mask, which is was mostly able to do--but when you are tired, you can make one too many false moves and the bullies see your weakness and go after you. I'm pretty sure all bullied kids are poor, neurodivergent, gay, or otherwise in a group that cruel children can sniff out.
