Am I done for because I'm not college material?

In this day and age, so-called experts claim that college is the only path to success and great careers. I believe this to be somewhat true, but I hope there are alternatives that still lead to the promised land. I noticed that many billionairies/millionaries were college-dropouts or never went there, but ofc they are exceptional people and geniuses. I never did really good in high school and wasn't motivated. If i'm not the type of person who learns in classrooms and books, what else could I do? there's still the chance I might goto community college, but yeah I'm open for alternatives. Please help!
