I saw a few youtube videos explaining that electricity doesn’t actually travel through wires but directly to the bulb from the battery. I understood their explanation. But now I have a doubt. Since energy flows directly to the bulb, can I shield the bulb in some way such that the circuit is complete and even then the bulb doesn’t light up?

I’m not sure what these said videos are imply, but wires (or some equivalent) are necessary to complete an electrical circuit. This can be proven by removing the wires and finding the load is no longer powered. A light switch works in the same way, making a circuit no longer complete.
