Well, Aces or Kings only come to one player once in 221 hands. That means that either one having aces or kings is less than one percent chance since they play, what, almost every hand?

Plus, you can outdraw those hands too. So I'll say you had either a:

50% chance of winning with them having crap hands
40% chance of winning with them having a pair
5% chance of winning with one having aces
25% chance of winning with one having kings

so the last case happens one time, the second to last case happens one time
the small pair case happens eleven times, the high cards case happens the rest of the time in one hundred

that adds up to 45% chance of winning with the information you have
your pots odds indicate a call as long as you have at least 33% chance to win

in any case, just bring more money with you next time so that your stack is hopefully ridiculously larger than theirs ANYWAY so you won't be afraid to make the right call
