77 vs 55 is two made hands colliding before the flop, and the higher pair owns it: 77 wins 80.5%, 55 wins 18.1%, and 1.4% of boards chop — 4.4-to-1. The lower pair, 55, is drawing to the two cards left in the deck that make it a set; miss those and only a runner-runner straight or flush saves it, which is why it gets there just 1 time in 6.
Think in variance terms: 81.2% equity means 77 loses this all-in nearly 19 times in 100, so even a "dominant" spot is a coin you'll see come up tails plenty. Getting it in as the 81.2% favorite is correct every time; the 18.8% that goes the other way is math, not a misplay.
As the bigger pair, 77, your whole job is to get the money in before a scare card — there's no fold here and slow-playing only lets 55 realize its set equity for free. As the smaller pair, the discipline is recognizing when stacks are deep enough that calling off 18.1% equity is a leak, even though folding pre feels impossible.
