It is possible that there are Catholics who mistakenly believe that, but it is also possible you have misunderstood them. First, Catholic teaching is that baptism removes all sin, original and actual. This is not just Catholic teaching. It is also the traditional Protestant teaching. Here are some quotations from definitive Reformed and Lutheran confessions.
The efficacy of baptism is not tied to that moment of time wherein it is administered; yet, notwithstanding, by the right use of this ordinance, the grace promised [including the remission of sins; see 28.1] is not only offered, but really exhibited, and conferred, by the Holy Ghost, to such (whether of age or infants) as that grace belongeth unto, according to the counsel of God’s own will, in his appointed time. (Westminster Confession of Faith 28.6)
What does Baptism give or profit?
Answer: It works forgiveness of sins, delivers from death and the devil, and gives eternal salvation to all who believe this, as the words and promises of God declare. (Luther’s Small Catechism 4.5-6)
It is also the traditional Protestant understanding that baptism is to be administered to the infants of believers.
Not only those that do actually profess faith in and obedience unto Christ, but also the infants of one, or both, believing parents, are to be baptized. (WCF 28.4)
Of Baptism they [the Lutherans] teach that it is necessary to salvation, and that through Baptism is offered the grace of God, and that children are to be baptized who, being offered to God through Baptism are received into God’s grace.
They condemn the Anabaptists, who reject the baptism of children, and say that children are saved without Baptism. (Augsburg Confession 9.1-3)
This is consonant with the teaching of St. Peter (the first pope!).
Then Peter said unto them, Repent, and be baptized every one of you in the name of Jesus Christ for the remission of sins, and ye shall receive the gift of the Holy Ghost. For the promise is unto you, and to your children, and to all that are afar off, even as many as the Lord our God shall call. (Acts 2:38-39)
One reason for your misconception about Catholic teaching is you’re assuming that you mean the same thing when you say “getting saved” as Catholics (or others) mean when they speak about salvation. Salvation is contingent on perseverance. Lutherans and Catholics agree that it is necessary to persevere in faith to the end and admit that it is possible to fall away from grace. Calvinists do not believe a true Christian can fall away, but they say that all those truly regenerate will exhibit final perseverance (even if it is not visible to outside observers). The belief that it is impossible to fall away from grace after conversion no matter what is often referred to (pejoratively) as “once saved, always saved” (OSAS). You seem to be laboring under the misconception that Catholics believe in OSAS when in fact neither Catholics nor most Protestants believe this.
Now you said baptism is just a ritual. If it is just an empty ritual, why did Christ institute it (Matthew 28:19)? What is its significance to you?
