KK vs JT is about as good as a non-cooler gets for the pair: both of JT's cards are undercards, so no single card flips the lead. KK wins 83.1%, JT wins 16.6%, and 0.4% of boards chop. The underdog has to pair twice, make a straight or flush, or otherwise back in — which is why pairs stack undercards so reliably at a 5.0-to-1 clip.
Think in variance terms: 83.2% equity means KK loses this all-in nearly 17 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 83.2% favorite is correct every time; the 16.8% that goes the other way is math, not a misplay.
In practice, KK vs JT rewards aggression from the favorite and caution from the dog: KK wants to realize its 83.1% edge by getting value and denying free cards, while JT should lean on fold equity and position rather than hoping to win the pot at showdown about 1 time in 6.
