These requirements are same for both standards.
Based on standards "The organization shall validate any processes for production and service provision where the resulting output cannot be or is not verified by subsequent monitoring or measurement and, as a consequence, deficiencies become apparent only after the product is in use or the service has been delivered."
Additionally if we think verification as "inspection", you aren't required to implement 100% inspection however you are required to ensure sufficient confidence such as statistically valid confidence level. (e.g using statistical sampling plans for inspection). Also if we think validation as "test" to determine meeting specific intended use, you are not required to conduct 100% test (same methods may be applied in verification). I am a contractual auditor of DNV-GL, they have guidance which addressed: "This requirement applies to products that cannot be truly verified until they are in use (e.g. a match – as the only effective way to test whether a match will work is to strike it!). A business
must have confidence in the ability of its process
to consistently deliver and meet customer expectations. Processes may also need re-validation from time to time because conditions, people and materials can change. Retained documented information relevant to process validation is required and may consist of r
ecords of operator qualifications, materials used, equipment used, methods used, the work environment etc.
