No, calling foreign numbers costs the same in both your country and abroad. And it's usually more expensive on mobile networks, but that doesn't have anything to do with roaming.

I misunderstood, I read things again and you are right.

This isn't correct - these regulations only apply when roaming. In your home network the operator can charge what it likes for intra-EU calls.
