Not true, most of the composers were brilliant performers as well. Writing and more importantly publishing their compositions gave them extra income on top of lessons and performances. So often Beethoven Mozart or Chopin needed or wanted money, promised compositions to publishers to get it, then were late due to overpromising. Sounds familiar to my overpromising on data analysis then running into snags and getting highly delayed. Anyway, paganini was a virtuoso first and foremost, the closest analogy would be a modern player like Horowitz or argerich, although liszt was similar but composed way more than paganini
