55 vs KJ is the classic preflop race — a pocket pair against two overcards (one-gap overcards). The pair noses ahead: 55 wins 51.8%, KJ wins 47.6%, and 0.6% of boards chop. The unpaired hand has six outs twice over (any King or Jack), and with a little extra straight equity the whole thing sits within a few points of a coin flip.

Translate that into a decision and it's simple pot-odds math: counting split pots as half, 55 carries 52.1% equity and KJ 47.9%. Against a pot-sized shove you need about 33% to call and about 25% versus a half-pot bet — so KJ is comfortably priced in to get it all-in here.

How you play 55 vs KJ depends on which side you hold. With 55 you're not crushing, so keep the pot controllable and take the 51.8% edge to showdown when you can; with KJ, your equity is enough to continue with initiative but thin enough that bloating the pot out of position is a trap.
