Would ventalation help to prevent dampness in my bedrooms?

or for any council tenant ......

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
