If the universe was born from nothing
It is unclear if that is a useful description.
then what are the possible reasons that we don’t see the same amount of matter and antimatter now?
There is tons of literature about it. What did you read so far?
Your question is very general, and it doesn't make sense to write books about it here because these books have been written already. As basic introduction, the Wikipedia article isn't a bad start.

If the universe was born from nothing ...
As mfb already pointed out, it was not. Saying that it was is a widespread version in all pop-science presentations. The actual current model of Cosmology, the Big Bang Theory, is silent about any creation event. That is, we have a verifiable theory of what the universe was like at a point in the past and how it evolved to what it is today but we do not know what was going on previous to that point in time (and that point in time is NOT a creation event, it's a time when the universe was an incredibly dense, incredibly hot, plasma of unknown (possibly infinite) extent
