Sorry about my english, but from my understanding a WAP is just to provide wifi to computers and devices. But why people say it’s to connect to a wire network? this is something I don’t get

First, good call specifying that you are talking about networking.
Second, pretty much all internet for residential use enters the home over a landline of some sort: twisted pair phone wires, coax cable, or fiber optic. From there it goes to some sort of modem or termination. Sometimes that modem has a wireless access point built in, sometimes it doesn’t. If it doesn’t, then you need a way to get the signals from the modem out to your devices – that means a wire to a computer, a wire to a router with a built in AP, or a wire to a router that connects through more wires to access points somewhere else. Those wires are almost always some sort of cat5 or cat6 cable, with RJ45 connectors, and the signals are transmitted using the Ethernet protocol.
