Bet better than badly bloated mug (10)

I believe the answer is:

outgambled

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

'better than badly bloated mug' is the definition.
I don't know anything about this answer so I can't tell whether it can be defined by this definition.

'bet' is the wordplay.
I cannot really see how this works, but
'bet' could be 'gambled' (I've seen this before) and 'gambled' is found in the answer.
The remaining letters 'out' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...

Can you help me to learn more?
