Everybody isn't hacked everyday for the same reason thieves don't break into our homes daily. Our homes aren't fortress as well, and we aren't regularly robbed because thieves are minority and know that they can be caught anytime.
It doesn't mean that we don't need to care about security, but that there is far more people vulnerable than people hacking or burgling. We may be a victim someday, so we'd better be careful. But hardly our weaknesses will be explored everyday.
