No, it does't, not if you take care of your records, keeping them and the stylus clean and tracking in the recommended VTF range, and replace the stylus when worn.
I've been collecting records for over 50 years (mostly classical and jazz), and my oldest records still sound excellent. Records don't wear out like that: maybe if you play them many hundreds or thousands of times, but the vast majority of record collectors don't play any one record that much. That's a corner case of use.
