Unless you're underwater, yes.

Or if the bedrooms are much colder than the outside atmosphere.

Depends on where the dampness is coming from.

If its coming up the walls in an ancient place with no damp
course thats sitting in waterlogged ground, likely not.

If its due to unflued gas heaters in the bedrooms, yes it will.

If its damp in those because its even damper outside all the
time, no it wont. You need a dehumidifier in that situation.

usually yes. Not the best option in winter though.

As a general rule, usually yes. However it does rather depend on the
source of the dampness and where its showing up.

So for example if the dampness is caused by bridging (e.g. soil piled up
against the exterior above the DPC), the ventilation may reduce the
symptom, but not fix the cause.

could be an old slate or caithness slab DPC ....

Depends on the source of the damp, e.g.
Penetrating rainwater,
Penetrating groundwater,
Condensation.

Condensation is a common source of moisture in bedrooms.
It happens because the air is too moist for coldest surfaces
in the room. This is either because the air is abnormally
humid, or because there are some surfaces which are particularly
cold (or both).

Ventilation and heating will help in the case of condensation,
but there may be far more effective ways depending on the
cause of the condensation, or you could end up unnecessarily
wasting energy in leaking out warm air are poor building
insulation.

You haven't given enough detail.

IME you need to maintain a temperature of around 17 degC to avoid
condensation and, in some structures, that ain't easy

Depends on how humid the place is. Thats quite
a high dew point, but you may be referring to the
temperature of the air, not the coldest surface.

and, in some structures, that ain't easy

Again, it depends on the situation, not hard in summer.
