Liquid oxygen is not flammable! It does however support vigorous combustion in anything even remotely flammable (like road tarmac, or human beings). That is because is is very reactive indeed. Being in liquid rather than gaseous form simply increases the concentration & availability of the element.
Not all gases are flammable. eg carbon dioxide, nitrogen or helium. Flammable gases are those which react easily with oxygen in the air to cause combustion... such as hydrogen, methane or propane etc. Even flammable liquids are flammable only because they give off a flammable gas at temperatures below.
