Course going around accommodation is enjoyed by those prepared to take a risk where the balls might land (8)
I believe the answer is:
roulette
'course' is the definition.
The answer and definition can be both acts as well as being singular nouns.

I cannot understand how the remainder of the clue works.
Can you help me to learn more?
(Other definitions for roulette that I've seen before include "Gambling game with small ball and revolving disc (8)" , "it's a gamble" , "Wheel of fortune" , "Game of chance with small ball" , "Whirling numbered wheel" .)
