If your oil level is full and you have low oil pressure it can be nothing more than a defective oil pressure sending unit or defective gauge. But, it can also be a weak oil pump. I would replace the filter first thing and add enough oil to reach the full mark and see if the condition goes away. If not, then replace the oil pressure sending unit.
It means you have low oil pressure. Low oil pressure means you will destroy the engine if you keep running it with low pressure.
The low oil pressure could mean that the vehicle is low on oil. More than likely the oil is leaking from the oil pan gasket.
It means you need to add oil that your oil is low
Low oil, low oil pressure, failed oil pressure sensor.
It can mean you have low oil pressure and it can mean that the oil sending unit is bad. Do not ignore this and have this checked out by a trusted mechanic.
no oil or low oil pressure
If check gauges is lit and the oil press gauge is low, you have low oil pressure or a failed oil pressure sending unit.If check gauges is lit and the oil press gauge is low, you have low oil pressure or a failed oil pressure sending unit.

No I would not expect low oil pressure to keep the engine from starting. Depending on how low the pressure is it might not be a good idea to run the engine much until the low oil pressure problem is corrected. Since there is no gauge built in on that year Celebrity I assume that the oil pressure light is on. Low oil pressure can be caused by a number of problems including failing oil pump, clogged oil filter, low on oil or loose bearings as well as a failing oil pressure sensor. When the pressure sensor fails it tends to show low oil pressure and if that is the cause then replacing the sensor can fix the problem. If it were my car I would first hook up an oil pressure gauge and find out what the pressure is before I attempted to fix the problem. Pressure should be at least 30 psi.
It means low oil pressure or possibly no oil at all.
