Q: Turning 30s is a milestone because it implies I'm no longer that young. この表現は自然ですか?
A: × Turning 30s is a milestone because it implies I'm no longer that young.
✓ Turning 30 is a milestone because it implies I'm no longer that young.

Just a tiny correction from "30s" to "30". (or it could be 36 or 39 or whatever age you think divides youth from middle age)

Being in your "30s" is a state that happens continuously over the period of a decade.

The word "turning" here implies something that happens only once at a specific point in time and then is done. Milestones are also things that are reached only once and are not done continuously. When you talk about turning 30, you generally mean the day of your 30th birthday.

So your original sentence sounded slightly odd because you used words related to one-time events to describe a state that someone is in for an extended period of time.

Hope that makes sense as to why it sounded unnatural.

Q: What are milestone birthdays ?
A: Milestone birthdays stand out more than other birthdays for either spiritual reasons or when new abilities are acquired.

16 is seen as a milestone birthday in american culture, also known as a "sweet sixteen."

18 is a milestone because at this point you are officially an adult. So you can sign up for the military, vote, do porn, etc.

21 is a milestone birthday because you can legally drink! KANPAI!

25 is a milestone birthday to some because it is makes you a "quarter of a century." (And you can officially rent a car!)

30 is a milestone birthday also known as the "dirty thirty" because it's the end of your 20s, which can be an end to your youthful/fun/messy life and more of an intro to a mature way of living.

Some people see multiples of 10 (such as 20, 30, 40, 50) as milestone birthdays. Other people see multiples of 5 (25, 35, 45) as milestone birthdays.
It is up to the person's interpretation.
