I wouldn't say the UK gaming law is vague but it is complicated.
Basically unless you're a charity you'll need to be licensed.

Do I need a licence if I am based abroad?
You do not need a licence from us to run a remote gambling service if all of your
remote gambling equipment is located outside Great Britain.
If you are based abroad and want to advertise your gambling services in Great
Britain, you must be based in a whitelisted country or a country mentioned
in the Gambling Act 2005.
That being said, it's still probably a good idea to get a license.
