Firstly, vaccines aren't perfect -- they significantly improve your chances of not catching COVID, and having less serious problems. It is better if (almost) everyone gets the vaccine, which will reduce cases of COVID.
Secondly, I'm getting the COVID vaccine not because they believe that there is a high risk of getting serious COVID myself, but to help others -- some at-risk people can't get the vaccine at all, and immune-suppresed people are still at significant risk post-vaccine (although still lower risk than without).
