As St Therese says, our vocation is really the way we express God’s love, whether that’s religious life, marriage, or consecrated single life. This is distinguished from a career or going to a college. So no your choice to go to a bible college would not be.
That being said unless it is through a Catholic program or bible study, I would take precautions. I had Evangelist/Protestant friends attend a Bible school after college and it was more geared toward making them evangelists/missionaries for their own church. These schools also teach a non-Catholic Bible, which leaves room for denouncing the Catholic faith due to differences in interpretation, lack of Catholic books from the old testament, and a lack of heed to natural law and tradition which helps us as Catholics better truly understand Scripture.
If you have a desire to better know the Bible as a Catholic I would visit a Catholic library or bookstore for reading guides or see if your church has a men’s/women’s Bible study. If you desire to be a missionary/evangelism there are numerous Catholic groups that do this including FOCUS and Lifeteen.
