@Asura 333 Travelling between worlds comes at a cost. The greater the being travelling, the greater will be the cost. Take the example of moving a heavy object from point A to B. Lighter the object , less energy and force needed to move it.
These so called goddesses/gods of another world are powerful but not enough to bring in a strong being from another world. That's why they always go for some random weak guy from other world and train him/her to become strong.
The rules of a world doesn't apply to a being of another world so they grow quickly and easily.
