The Lightning network is still in it’s infancy and not very user friendly to a non-technical person. If you would like to try the Lightning Network and not run a routing node there are custodial wallets you could use to get the hang of it. That being said you should learn how to setup a routing node, it’s fun and you can make some Satoshis along the way.
Lightning Network is based on a technology called payment channels. Two peers in the network can open a payment channel with each other by making an on chain transaction. All these channels create a web in which the peers in the network can transact threw one and other without needing to trust any of the participants. This way the network can handle thousands of transactions per second near instantly and for very low fees.
