I suspect they're angling for a Jon Snow xoxo Daenerys Targeryan lovefest to create a united front against the Night King's incursions.
How the final battle plays out is anyone's guess. Based on the show's history, George R.R. Martin seems to believe in the concept of women out surviving their husbands.
All female gendered characters should probably have lower odds under male gendered characters.
I would guess Daenerys will survive to unite the clans & rule after Jon Snow perishes(again) in the final battle.
This is obviously not the case in this series. While historically true, GoT does not represent historical facts.
The whole series, women play a very powerful role. Just look what position Cersei got herself into. Daenerys. Look where Sansa is heading and even the little kid.
EDIT: I may have misinterpreted what you were trying to say. Lower and higher odds can be confusing (is lower or higher better odds?)
It's true that women hold a lot of power in GoT, but they do not rule de jure.
They have influence, but do not rule.
I believe neither Jon nor Dany will rule Westeros, George will kill them.
Who will? I have no idea.
I'd bet on a higher odd, since that's what George is going to do.
