Does uma vez que literally mean one time that?

Literally, yes, the words are:

• uma = one / a
• vez = time / occasion
• que = that

But as a fixed expression, uma vez que does not usually get understood word by word. It functions as a connector, much like:

• once
• since
• given that

So it is better to learn uma vez que as a chunk rather than translating each word separately every time.
