Jcontrols is right.
A gas fire uses a HUGE amount of gas compared to a gas cooker. There's no comparison.
If you used a gas cooker in an hermetically sealed room you'd run into trouble sooner or later though. That's why you should never use the oven to warm up the kitchen.

All gas appliances have to have adequate ventilation to suit their needs.
For complete combustion to occur, one unit of natural gas (methane) needs 2 units of oxygen (or 10 of air as oxygen is ~20% of air) to end in one unit of carbon dioxide and 2 of water vapour.
Incomplete combustion occurs when there is insufficient oxygen, and instead of carbon dioxide, carbon monoxide is produced. The implications of this are very dangerous as carbon monoxide is poisonous and competes with oxygen in the haemoglobin component of red blood cells supplying oxygen to the body from the lungs.
Appliances up to 7Kw can theoretically rely solely on "adventitious ventilation", this is ventilation that is naturally occuring through gaps under windowsills and around door frames, but anything above 7Kw will require a permanent ventilator grille to outside air.
standard cookers are flueless appliances and are usually within this range, but must have a minimum room volume of 10 cubic metres and be in a room with an openable window or door to take all these variables into consideration.
Cooker hoods are generally provided to extract water vapour and pungent cooking smells to minimise the effect of condensation and its resultant dampness effects (mould) in kitchens which satisfies Part F of Schedule 1 of the Building Regulations (England & Wales) 2000.

If there is no flame to burn the gas and the area is not well ventilated then it is dangerous. And I wouldn't recommend ever falling asleep while a gas stove is on (or any stove for that matter). If your electricity goes out then use more blankets. And if you can cuddle up with someone naked and share the body heat (good excuse to get naked with a significant other).

Gas range? These appliances use a tiny volume of gas compared to heating units! :-)=

Don't all rooms containing a gas appliance have to be properly ventilated?

Because the flame is combusted in open air.
