Hi
I recently let someone from apple support share my screen to help resolve an issue. Ever since I have been really worried that they can now control my Mac when I'm online or at least they can see when I type in bank details or similar. Is there a risk

There is no risk, also check here for peace of mind........
Turn off screen sharing on your Mac
On your Mac, choose Apple menu 
> System Preferences, then click Sharing.
Deselect the Screen Sharing checkbox.
Turn Mac screen sharing on or off - Apple Support
