I dunno if it's immature in and of itself, but people who are regularly sarcastic tend to be insecure ime. Especially those people who are proud of their sarcasticness, and even characterize themselves as being sarcastic people. They tend to be either young or unfunny.
Personally I hate the word "immature" and the idea that it can be meaningfully measured.
I've seen here on TypoC that some people equate "passive-aggressive" with "immaturity," and sarcasm is a hallmark passive-aggressive way to counter a point.
Besides, it's not like they have anything on them that makes them any less "mature" than you, right? It's not like anybody can return criticism on their thoughts and actions, too. No other critics like him in the world, right?
I've heard it stated as the "Law of the Boomerang": "Always treat others as you'd have them treat you, because your actions are like boomerangs. Someday they'll come back to you."
Anybody unfamiliar with the quote...Patch the Pirate Down Under. It's a Christian audio adventure for kids voiced mostly by kids. And it attracts small kids like moths to flame. And I've heard devoted would-be Baptist preachers describe the result as a "level of hell." And it's part of a series just one short of 30 unique installments...plus 7 gift boxes.
I LOVE sarcasm. I'd rather be immature and sarcastic than too dense to pick up on sarcasm. Or worse yet a [insert derogatory word] that doesn't appreciate sarcasm.
It can be overused though. But it's great in doses.

If I buy a tasty Hostess apple pie....
FRIEND: You gonna eat that?

My friend is driving us to a concert...
FRIEND: The directions say to turn left, so I guess I should turn left?
ME: No, go right, maybe Google is just fucking with you.
I'm smoking in a designated smoking area at a theme park...
STRANGER: I personally think that's a disgusting habit.
ME: What? Pushing your opinion on someone who obviously doesn't give a shit about it? Yup, terrible habit.
A friend is rushing me to finish a project he was supposed to do...
FRIEND: Um, can you like, you know, speed it up please??
ME: Um, can you like, you know, eat a dick?
My Mom is tying about three knots in the garbage bag to be placed on the curb...
ME: Why are you tying so many knots?
MOM: I don't want the animals getting into it!
ME: Yeah, because that's how Racoons get into garbage bags, by untying knots.
I don't know if that's sarcasm or not, nor do I know what this says about my maturity level. All I know is that I enjoy.
