Is it true that people vaccinated against chickenpox have a lower risk of developing shingles than people who had natural chickenpox infection?
Partly. The CDC states that children vaccinated against varicella have lower rates of shingles than children who had natural chickenpox, but this covers only children. Other sources raise the concern that chickenpox vaccination could increase shingles in older or later cohorts, and one notes the vaccine itself can cause latent infection and later shingles, so the evidence is partial and points in both directions.
