In keeping with the setting of Star Wars: Galaxy's Edge, Rise of the Resistance is set on a single, repeating day in the "in-universe" year 34 ABY (set between The Last Jedi and The Rise of Skywalker).[17] Following the Battle of Crait, the last vestiges of the Resistance have retreated to the planet Batuu – once a thriving trader's port on the edge of Wild Space, long-since bypassed by hyperspace travel. There, the regrouping Resistance has set up a hastily-constructed makeshift base in the wilderness outside of Black Spire Outpost, repurposing ancient tunnels once home to an unseen civilization.[18] Defected Stormtrooper and Resistance loyalist Finn has infiltrated the Finalizer – the First Order Star Destroyer belonging to Kylo Ren – and has learned that Ren is aware of the Resistance's hideout on Batuu and plans to occupy the planet to ferret out the Resistance forces. With word of the encroaching threat shared back to the Batuuan Resistance faction, the Resistance has made the decision to evacuate the planet and meet on the mid-rim planet Pacara where General Leia Organa plans to regroup and stage a final stand against the First Order.

(from the Wikipedia page).

On the ride, when the Resistance fleet turns up above Batuu, it's pretty similar to the fleet that we see in The Last Jedi (probably because the CGI models already existed), but there's a Mon Calamari cruiser (Allegiance call-back), a Nebulon-B escort frigate, and a couple of StarFortress SF-17 heavy bombers.

However, the biggest ship the Resistance seems to have by the time they're on Ajan Kloss, that we see when they take off for the Battle of Exegol, is the Tantive IV. So either they took heavy losses on Batuu (I don't think so, given the triumphant nature of the ride), or that final stand mentioned that was planned on Pacara went south very quickly.
