Correct up to a point.

Blowby at part throttle may only be 20-50% of the blowby at wide open throttle.

So if the "breather" being a filter, or a tube going the airfilter isn't large enough to handle the volume of blowby, then something usually gives.
Either the dipstick gets pushed out, oil leaks develop, or both.
