No, that’s not how local networks work. Whether wired Ethernet or wireless with WiFi/Bluetooth, every packet sent from one device or from the router/gateway is seen by every other device in the same network (the same router or gateway boundary). By default, devices choose to act only on the packets addressed to them, and ignore the others. This is why using HTTP (not HTTPS) on a public WiFi network is a risk because everyone else around, if they want to, can sniff and read all the packets and know what exactly you’re up to.
