How hard is it to date after having a baby?

I’ve been married for four years since I was 21, now 25. We were together all of college and got married. We just recently had a little boy who is my whole world. My now ex-husband decided he wanted a divorce not long after, so we aren’t together anymore. My friend told me I should have waited till my 30s to have a kid because I’ll never find a guy to date now because having a kid hurts my chances dating and no one wants to raise someone else’s baby. On top of an already devastating situation this stung. I am sure it’s true but how bad are my chances gonna be of finding love again?

So essentially I’m gonna be single for the rest of my life? And the only man in my life will be my son?
