" Almost completely wrong (ask your parents, astura).
It is true that the Catholic Church did not emphasize the Old Testament (OT). They instead emphasized the New Testament (NT) (both NT and OT are parts of the Bible). We were educated about the Protestant Reformation and the differences in faiths. I think the problem is that the Catholic Church has generated so much structure and associated doctrine that they barely have time for OT! In any case, much of this fell into one or more of my Church History classes, hardly my favorite subject.
FWIW I had a completely Catholic education from grade school thru university and nobody ever refrained from referencing the Bible. I've long since left the faith but I kept my sense of humor. Here's my favorite OT joke:
Q: Who's the strongest man man in the Bible (hint: it isn't Samson)?
A: Abraham. He tied his ass to a tree and walked up a mountain!
As for the Latin mass, yes it was there, and if you wanted to know what was said then you could always find out - nobody was hiding anything. I was an "altar boy" (assisted the priest in the rituals) so I learned the Latin mass and, since I went to Catholic schools, I later studied Latin. Latin is a useful language to know as an English speaker and it helps in understanding the so-called "romance languages" (it even aids in understanding English - many word roots are from Latin).
FWIW the traditional Latin mass is still celebrated! Some have stuck to the old Latin rites b/c of their love of the old rituals, the music is better in Latin (got to agree on this one!), etc.
