It isn’t about absolute peace, that is practically impossible.
It’s about relative peace, worldwide number of conflicts, casualty rate by population, geographical spread of conflicts, etc.
What is unprecedented is your chance of being killed in war has gone down substantially and stayed down after WWII. The types of conflicts have changed, civil wars now dominate, other types have gone down significantly or have been eliminated. There have not been conflicts between major military powers.
