That doesn't actually seem like a huge achievement. Inflation is the rate of change so if you stop creating as much money out of thin air, then it's not really a surprise that prices don't increase as much.
Historically, it has been.

You're confusing money supply and price levels. Inflation measures the latter. You can have constant money supply and stable prices, inflation or deflation. And since most money is privately created, controlling how much money is and isn't created "out of thin air" is actually quite challenging.
They're closely related.

It's the central bank which controls the interest rates, the reserve requirement and other stuff which affects it.
But not the same. In this case, the difference is material.

Affects. But does not control. That's what makes it challenging.
To my memory, a soft landing from 5+ percent inflation has been achieved precisely once in modern monetary history. (And not for lack of trying.)
