Let there be two co-centered circles.
If I'll roll the big circle so it would complete a 360 turn - the

By this you must mean the distance that the center of the circle will
cover. Points on the circumference don't travel that same distance.

If I'll roll both of the circles simultaneously (like rolling a disc)
the small circle would also complete a 360 but it will travel the
distance of the bigger circle.

You mean the small circle's center travels the same distance.

How can it be ?

Easy. The small and large circles have the same center.
