We will be connecting flights in Amsterdam between the United States and Central Europe. Is a little more than 4 hours really enough time to fit in a tour of Amsterdam as the Schiphol airport website suggests?

How does customs, passports, and security figure into this? In Rick Steves fashion, we only plan to have carry-on luggage. I suppose we can put the luggage in a locker for a few hours. Do either passport checks or luggage security screens happen during international transfers in Schiphol no matter if one leaves the airport or not, or only when leaving the airport?
Thank you.
