Any idea how to fix this wobbly cassette? The bike is new and it’s making it a nightmare to calibrate the rear derailleur

You can’t that’s just the way those 7 speed and below screwy hub cassette combos are.
Bent axle. Easy to check if you have a set of cone wrenches.
Poorly machined hub/cassette body…non-concentric. It shouldn’t really affect things much. The “fix” is get a better quality wheel.
Cheaper freewheel setups also wobble. Ignore it.
I see nothing wrong there.
Just ride it
Mechanic here, wobbly free hubs are normal for budget wheels and cassettes, very occasionally, with certain kinds of freewheels such as the shimano tourney ones, the rivets on the back can cause the freewheel to sit wonky against the freewheel body. Though it’s much more likely to be an indexing/ bent hanger/ sticky cable issue. There’s plenty of indexing videos on YouTube
This is probably not your issue. 8 speed cassettes are very tolerant to misalignment. If this was a SRAM 12 speed, you would have a real problem.
thats likely a freewheel, not a cassette. and no, the wobble does not really matter for indexing.
low end bike parts are always harder to dial in because their adjustment features are crappy made as well. like having a nut for the cable clamp instead of an allen bolt.
Axle is bent
It’s definitely the wheel, you can see the hub wobbling as well.
Does the cassette follow the same movement as rear hub when spinning? In this video it appears static.
This is probably a freewheel, not a cassette. That wobble is very normal and not of concern.
the wobbling is not an issue. indexing the rear derailleur is likely tricky because of sticky cables and/or bent rear deraileur hanger
If you’re not too attached to indexed shifting change to a friction shifter. Takes a lot of headache from the rear derailleur calibration.
