Is it true you cannot master a language (speak like native) after around a certain age?

I heard this a few times but think it is false. Does this limitation really exist and is it really that hard to overcome?

You can master a language pretty well after the age of 10 or so, but studies have proven that you will [almost] always make small mistakes in grammar and have a slight accent, and be less likely to pick up subtle grammar misnomers.

It is also harder to pick up a language after this age, but it is still possible with study, concentration and immersion.
