The range this is computed against
The classic recreational flatting range — a player who "likes to see a flop". Any pocket pair, any suited ace, king, queen or jack, every playable suited gapper, all the offsuit aces and a stack of offsuit broadways. Around half of all hands, and almost none of them are folded before the flop.
calling station — 670 combos, 50.5% of all starting hands: AA, KK, QQ, JJ, TT, 99, 88, 77, 66, 55, 44, 33, 22, AKs, AQs, AJs, ATs, A9s, A8s, A7s, A6s, A5s, A4s, A3s, A2s, KQs, KJs, KTs, K9s, K8s, K7s, K6s, K5s, K4s, K3s, K2s, QJs, QTs, Q9s, Q8s, Q7s, Q6s, Q5s, Q4s, Q3s, Q2s, JTs, J9s, J8s, J7s, J6s, J5s, J4s, J3s, J2s, T9s, T8s, T7s, T6s, T5s, 98s, 97s, 96s, 95s, 87s, 86s, 85s, 84s, 76s, 75s, 74s, 65s, 64s, 63s, 54s, 53s, 43s, AKo, AQo, AJo, ATo, A9o, A8o, A7o, A6o, A5o, A4o, A3o, A2o, KQo, KJo, KTo, K9o, K8o, K7o, QJo, QTo, Q9o, Q8o, JTo, J9o, J8o, T9o, T8o, 98o

Against a loose-passive calling range (670 combos, 50.5% of all hands), JTs runs at 49.4%. It wins 47.8% of runouts outright, loses 49.0% and splits the remaining 3.2%. Your own two cards remove 62 of those combos before the flop is even dealt — a blocker effect this number already accounts for, because every combo containing one of your exact cards is stripped out of the range first. You are ahead of only 197 of the 608 combos still live (32%) — the rest of the range is level with or in front of you, which is why the figure sits below even money.
The range behind this number is not a guess. The classic recreational flatting range — a player who "likes to see a flop". Any pocket pair, any suited ace, king, queen or jack, every playable suited gapper, all the offsuit aces and a stack of offsuit broadways. Around half of all hands, and almost none of them are folded before the flop. JTs's worst spots in it are JJ (17.8%), QQ (18.3%) and KK (19.8%) — and its best are T8o (74.2%), T9o (74.1%) and J8o (73.1%). Across the whole range JTs's equity swings from 17.8% at the bottom to 74.2% at the top — the single 49.4% headline is the combo-weighted average of all of it.
Facing 50.5% of hands, JTs has 49.4%. A wide calling range gives JTs room to make hands, but not room to win a preflop all-in — take the flop, then decide.

What hands are in a loose-passive calling range?
105 hand classes and 670 combos — 50.5% of the 1,326 possible starting hands. By combo count it is 12% pocket pairs (13 pairs, 78 combos), 38% suited hands (64 classes, 256 combos) and 50% offsuit hands (28 classes, 336 combos). That shape is why JTs runs at 49.4% against it rather than against a random hand.
Does JTs do better against a wider or a tighter range?
Wider, almost always. JTs has 49.4% equity against a loose-passive calling range (50.5% of hands) but 32.3% against a 4-betting range (3.2%). Equity against a range is mostly a question of how many weak hands the range still contains — which is why the same holding can be a monster against a button open and a fold against a 4-bet.
