Re: "How to control all devices : If I don’t have a Mac can I still control all my devices from just my phone"

You can remotely control your other Apple devices with your iPhone.

Apple support's article: Control a nearby Apple device with iPhone - Apple Support

says:

1. "Go to Settings  > Accessibility > Control Nearby Devices, then tap Control Nearby Devices.
2. The device you want to control must be signed in with the same Apple ID and connected to the same Wi-Fi network as your iPhone.
3. Choose the device you want to control, then tap a button.
4. Button names correspond to the controls on your device. Tap  to see your options, including media play controls."

"Tip: To quickly turn on Control Nearby Devices, add this feature to Accessibility Shortcut.

To stop controlling the other device, tap .

All the best :-)
