Not all smokers develop COPD. About 10% are non-smokers.

Explanation:
Not all smokers develop COPD because smoking is a major risk factor, but not everyone exposed to it ends up with COPD. The disease results from long-term airway and parenchymal damage caused by multiple factors, not just smoking. Importantly, a substantial minority of COPD patients have never smoked—roughly about 10%—which reflects other causes such as biomass fuel exposure, occupational inhalants, environmental pollution, and genetic conditions like alpha-1 antitrypsin deficiency. So the statement is true: COPD can occur in non-smokers, and not all smokers will develop the condition.
