Caveman and accidental lottery god (10)

I believe the answer is:

troglodyte

I'm a little stuck... Click here to teach me more about this clue!

'caveman' is the definition.
(I know that caveman can be written as troglodyte)

'accidental lottery god' is the wordplay.
'lottery god' anagrams to 'TROGLODYTE'.
Though, I'm not clear how this is indicated.

'and' is the link.

Can you help me to learn more?

(Other definitions for troglodyte that I've seen before include "Cave-dweller" , "low-lifer" , "Introvert" , "Recluse" , "Cave dweller" .)

I've seen this clue in the Sydney Morning Herald.
