Is it true that every device on a LAN will see/record the MAC address of every other device on that LAN?

Greetings all,

I had a quick cyber-security fact that I wanted to validate as accurate. Is it true that every device on a LAN will see/record the MAC address of every other device on that LAN even if there is no direct communication between devices? So if I connect to WiFi then the MAC address of my device is being seen/recorded by all the other devices that are connected to that WiFi network, and all the MAC addresses of those other devices are being seen/recorded by my device?

Thanks in advance for any replies.
