How hard is dating 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?
