I mean when we lit the stove, LPG gas picks up fire but does not go down to the cylinder why??

Your burner is designed so that the gas mixes with the air and burns in a controlled manner. It acts like the bunsen burner in your chemistry lab.
If you light the gas anywhere else eg. from a leak in the hose or at the tank's valve, it will expode. So pls don't use light to detect any leaks from the gas hose or tank.

The get a fire you need 3 things:
Oxygen, heat and a flammable substance. Oxygen and heat are the two missing parts in the cylinder. Because the pressure in the cylinder is higher, oxygen can't get in the cylinder. The flames and the hot air go up, so the cylinder doesn't gain heat either.

The container pressure is one factor, but actually it is the absence of oxygen in the cylinder that inhibits combustion.
Conversely, if you are using a propane tank (instead of acetylene) with oxygen for cutting metal it IS possible for the flame to flash back into the cylinder. Use of a flashback valve prohibits this.

The gas regulator & the valve on the cylinder head are designed on the basis of one way gas flow. They don't let the oxygen enter the cylinder & without oxygen the combustion is not possible.

since the cylinder is closed, there is no entry for the spark to catch fire inside the cylinder.

Pressure keeps it coming out, but fire needs oxygen to burn, so you're safe either way.

because there's some kind of gas mking it go up and preventing it from coming down.

It's because of the lack of oxygen.
