I've heared that it was prowed to be false, but is still used for demonstration and easier explanation. Is it 99% sure that electrons are flying around the atom.

Chemical bonds of "different types" actually form a range of strengths and there is no really clear delineation between the types. In our effort to simplify the concepts we may have painted too sharp a difference. Comparing Ionic and Covalent bonds in general terms can fall apart when you start to look at specifics.

As a rule of thumb, the more a bond is like an electrostatic attraction between unlike charges, the more energy it takes to disrupt. Thus the assertion that ionic bonds are stronger than covalent.

Disrupting the bonds in a sugar molecule will take considerably less energy. Disrupting the bonds in something like table salt takes a lot of energy.
