quantum field theory - How many quarks in a proton?



I am confused by different papers I have seen on the internet. Some say there are three valence quarks and an infinite of sea quarks in a proton. Others say there are 3 valence quarks but a large amount but finite number of sea quarks(quark, antiquark virtual pairs) in the proton


What is the answer? are there an infinite amount of quarks in a proton at any one time? how can this make any sense?
