12% odds for 3 years seems fairly resonable for a manned landing.
Your statement of "Starship will never go to Mars. It's very unlikely it will go to the Moon" which sounds like it includes even unmanned test landnings is a quite different beast.
There are more possible bets on manifold, you do you.
I'm not really a betting man, but given the HLS budget is spent and most of technology is not nearly developed I'd say even an unmanned Moon landing is at least 5 years and $10 billion away and Mars is pure fantasy.
What does that mean? Starship is basically self-funded by SpaceX and the amount of money they got for the HLS contract is something they blew way past even before the contract, that doesn't make much sense.
