When flights get cancelled because of heavy winds / bad weather, why is it only e.g. 10% of all flights and not 100%? Isn’t either too dangerous so no plane can take off or it’s safe so they all can take off ?

Depends on the airport and the specific conditions

Many airports will have primary runways pointed one direction and secondary one pointed another. For example Newark has two long North-South runways and one short East-West runway, most planes use the two parallel runways under most conditions with one for takeoffs and the other for landings, but if there are strong Westerly winds then they can’t use the two main runways and have to use the much smaller one for both take off and landing. This cuts their capacity to less than half but still leaves them with some capacity.

Which planes make it in depends on what the airlines need. If they need your airframe for an international flight in the morning it’ll get priority over a regional flight which is much cheaper for them to reschedule
