Yes, Jesus (the Messiah, the Lord) is letting a Samaritan know that salvation (i.e. Jesus Christ) is from the (Biblical) Jews, because he was born from Mary, a Jewish woman. This obviously has nothing to do with the religion of modern Judaism, if that's what you are trying to imply.
Honestly am not sure how you don't know that Christianity revolves around the idea that "salvation is through Jesus Christ," but anyway I hope you learned something today.
If you have any other extremely basic questions about Christianity for me feel free to ask, but I really would just encourage you to read the Bible instead.
