At first glance, it looks like you're forgetting to account for board cards when you're counting Villain's combos.

E.g. You list { KTo, KJo, KQo } as having 12 combos.

There are 2 K's on the board, so 6 combos available to Villain.


I recommend using Equilab (free to use) or some other poker calculator when you're looking at this stuff.
There are tricks and things to memorize so that you can do this more quickly on the fly, but for a beginner, I say just use a calculator while you study, and feel free to explore it and use it to answer questions.
