Parkinson's disease affects approximately 1 in 100 people over the age of 50.

"the idea is that 1 in 100 over the age of 50 have Parkinson's disease" (said at 0:15:19)

A systematic review and meta-analysis of global epidemiological studies shows that Parkinson's disease (PD) prevalence increases markedly with age but does not reach 1 in 100 (1%) at age 50. For individuals aged 50–59 years, pooled prevalence is 107 per 100,000 (~0.1% or ~1 in 1,000). The 1% threshold (approximately 1,087 per 100,000) is reached in the 70–79 age group, with rates rising to ~1.9% in those over 80. Stating that 1 in 100 people over 50 have Parkinson's overstates the prevalence for individuals in their 50s and 60s by several-fold.
