If you're referencing Celtic and the Wolf, those were explicitly depicted as larger and stronger than the average Predator on purpose (stronger but not larger in Wolf's case). On top of the fact that the Xenomorphs in AVP and its sequel were different from the Xenomorphs in Alie, Aliens, Alie 3, Alien': Resurrection and Alien': Isolatio (strikingly similar to the Covenant Protomorph in reproductive virility, however), and were also weaker and smaller. They are actually about dead even (Again, excluding Wolf and Celtic predator) with Xenomorphs, if not struggling a little bit where a Xeno would have no trouble. Remember, that immediately after Grid breaks free from the razor net, the Alien tackles and pins Celtic with essentially zero effort whereas the Celtic was using every bit of his strength and still struggling a bit to swing Grid around. Likewise, Grid impaled and lifted Gill with no effort, and after head-bitten, is tossed aside like a ragdoll toy - far more easily than Celtic lifting Grid (and even Wolf lifting the Midget Xenomorphs) which, in the context of the filming of that scene indicates an endeavor of great significance for the young Predator, more so than the way Gill is trivially impaled and thrown aside by Grid's tail. Ergo, while Predators make use of advanced technology and physique far superior to that of a human to eliminate their Xenomorph prey, Xenomorphs - even Drones - have the unnarmed, raw strength advantage. An unarmed Predator would not be able to overpower a Xenomorph without his armor and weaponry (unless we're talking about Berserker Yautja, but that's an entirely different discussion), and would quickly have his head lopped off or impaled to death on the Xenomorph's tail, pinned down and head-bitten, or receive a death-dealing throat-slash from the Alien's claws or tail. There is simply no way for a Predator to overpower a Xenomorph unless he were to somehow sneak up on it, and even then he would almost be certainly eliminated by the Xenomorph's tail. The simple fact that the Xenomorph even has such a powerful tail pretty much means an unarmed hand-to-hand fight between a Xenomorph and a Yautja would go to the Xenomorph by default. They probably have more musculature tissue in their tail than a fully-grown male body-builder has in his entire body.
It's a common misconception, most people in general think the Predator is stronger by default because of their technology and their similarity to humans. Most people go their entire lives thinking Predators are stronger. It's super understandable and a very common error. But look at this way - Predators don't NEED the extra strength, they've got shuriken, smart disks, plasma cannons, interstellar travel, armor plating, mines, etc. They also have civilization, culture, heritage, and intellectualism. Something no ALIEN has besides maybe the Queen. It's like humans vs. chimpanzees. Humans can outperform chimps on average and in general in most ways, like running a marathon, but if you piss one off it'll rip your gorram face off and shit down your neck.
