Not to be too blunt, but if you're new to writing short fiction and you're submitting (at least initially) to paying markets, then to some extent -- yes, you did sign up for a year of rejection. Most markets that pay more than a token amount probably take 10% or fewer of the stories they receive. For top-end markets, it's probably more like under 1% in general.
But nearly every short story writer starts with the rejections before getting the acceptances. And though it might sound trite, it really DOES make the acceptances feel special.
I hope this helps and that you hang in there!
