Sorry still trying to learn how to use fairlay and have some really noob questions.

I think I still have the mindset of using a sportsbook. Some of the stuff just does not make sense to me, for example this market

Question 1 - So looks like the odds for TNC to be reach grand final is 8.3 which make sense. but the odds against TNC to reach final is 19.867?(thats just too good to be true)

Question 2 - I see there is ODDS and OFFERED ODDS, is ODDS the actual odds for the bet?(that would make sense but if that is the case what is OFFERE ODDS for?)

Question 3 - I assume liability is the max amount you can bet?

Question 4 - What is the different between taker, market/taker, market maker?
My understanding is taker basically just take the available orders. Market/taker would take the available orders and create additional order if it can fulfill the volume you want. Market maker would create order for both side and basically try to profit from the margin.

Sorry if any of the these questions is dumb.
