Simple answer: yes. Since klm is handling amsterdam, they will be responsible for dealing with delays.
1h 40 seems like a reasonable transfer time though. Your biggest worry should be to enter the schengen area. I would advise you to do that asap and enjoy schiphol after getting through. Typically someone will be waiting at the gate with instructions if you arrive. Schiphol - Amsterdams main business comes from transfer traffic, so the airport is quite efficiently organized. You might want to study the airport layout to find your way.
