Does the Wi-Fi and data change automatically on the lte cell phone?

Shopping

I'm using my cell phone, but until now, I turned on the Wi-Fi and used the data if it didn't work, but after hearing about my friend, it works automatically even if I keep the Wi-Fi on

Is it correct that if Wi-Fi is enabled, it becomes automatic Wi-Fi and if not, it becomes automatic data?
