Bruh, bad win rate doesn’t equate to weak whatsoever, feats and matchups are significantly more important. Torkoal had a lot of losses but it got stronger training at Oak’s lab and managed to bring Brandon’s Registeel to its knees, plus the fact that Ash even chose to use it against Tobias shows that he trusts he’s a strong Pokémon, it did get one shotted but so did Heracross and it wasn’t gonna win a beam struggle against Darkrai. And Gliscor has had a lot of losses prior to training(Key word: Prior to training) but let’s look at each of them, lost to Gliscor as a timid Gligar which was obvious, tied with Barry’s Roserade who wasn’t necessarily a pushover(Beat Chimchar albeit weakened) lost to Snover(Significant disadvantage plus to give Chimchar two wins), lost to Torterra who was literally Paul’s ace alongside Electivire and he still managed to leave him panting and lost to McCann’s Scizor twice prior to training which was obvious given how much more experienced he is plus it’s part of Gliscor’s arc, Staraptor, Buizel and Grotle wouldn’t have done any better against McCann’s Scizor either. As for Torterra, that Electivire knew Ice Punch and was even giving Pikachu trouble, it took multiple hits from Bertha’s Hippowdon and even landed a Leaf Storm and apart from the Gliscor was the only one who could even damage Drapion(+Overpowered Cross Poison with Energy Ball) while Buizel and Staraptor got stomped so no Torterra is not weak. By your logic, Scraggy is stronger than Sceptile(48%) because he has a higher win rate. So yes on the basis that Gliscor was able to defeat Drapion while being poisoned and without too much worry is a great feat given how it plowed through half of Ash’s team and showcased a lot of great manoeuvrability such as essentially cancelling out the recharge effect of Giga Impact, etc and as for its loss against Electivire, wasn’t 100% plus Paul’s Electivire is a beast, none of Ash’s other Sinnoh mons apart from Pikachu and Infernape stood a chance
