Do you need Bluetooth for this controller?

I want to buy an Xbox controller that I use to play FIFA 20 on my PC.

I chose the following controller:

The controller is connected via an adapter by inserting the stick into the PC.

Do you still need Bluetooth? Because my PC has no Bluetooth, and can you connect a cable to this controller in an emergency and then play with a cable?

No. With this there's an adapter that creates the connection.

No, why else should there be a stick for wireless connection?

If that doesn't work, can the controller also be connected by cable?

No, your PC does not have to have a built-in Bluetooth function. The stick does that.

Of course, you can also play with cables.

I think so. Texhnolyze95 had written that this can also be done with cables

You can either use the controller wirelessly with the included stick, or you can connect it with a micro USB cable to the USB jack of the PC and use it above / via cable
