If a proton's m is 931 MeV, then how is it that its only made up of 3 quarks which m is only 9.6 MeV?

A m of a proton is about 931MeV but it says it is made up of 3 quarks, two up quarks and one down, which only adds up to 9.6 MeV, so either there must be more than that to the ration of 2:1, or there must be something else to it that comprises one proton.
