Does that mean she's well trained and/or experienced? Because they aren't the same thing.

You can train all you want with a practice dummy which strikes at you (or sparring with a friend), and you can practice spell-hopping through a "trap room"; it still won't prepare you for someone actively trying to kill you.

This is very much what we see here: being royalty, she likely had a professional swordsman train her for years in how to use that blade. Similarly, she probably spent years practicing 3-dimentional movement, likely while being attacked with practice weapons.

Her shortcomings become apparent in her fight, however: she has likely only sparred with a few people in her life, people whose tricks she knows and thus are predictable; this leaves her open when someone she doesn't know does something unpredictable - like leaping across the room, slashing across the ground or punching while using a sword.

I'd say Weiss is someone who has alot of training, but has little practical experience in battle, contrasting with the rest of the cast thus far, who all seem to have alot of combat experience, with possibly minimal or average formal training.
