All entirely true about those whom He was addressing.
Nothing in Catholic Holy Tradition nullifies the Word of God. The Catholic Church was founded by the Word of God, the Word Made Flesh, Jesus Christ.
Just as those He was talking of were founded by God the Father who brought them out of slavery into the Promised Land and gave them the Law as inscribed by the Hand of God - yet they nullified it as He observed.
Luke 18:9-14 To some who were confident of their own righteousness and looked down on everybody else, Jesus told this parable: “Two men went up to the temple to pray, one a Pharisee and the other a tax collector. The Pharisee stood up and prayed about himself: ‘God, I thank you that I am not like other men—robbers, evildoers, adulterers—or even like this tax collector. I fast twice a week and give a tenth of all I get.’ But the tax collector stood at a distance. He would not even look up to heaven, but beat his breast and said, ‘God, have mercy on me, a sinner.’ I tell you that this man, rather than the other, went home justified before God. For everyone who exalts himself will be humbled, and he who humbles himself will be exalted.”
