No probs, love helping. Basketball shoes have been trending towards greater minimalism so you actually have plenty of choices; thick soles + arch support are no longer the norm today.
One of the most minimal bball shoes available is the Nike Kobe AD NXT 360. For a size 9, the offset (heel-toe drop) is only 3.81mm. The forefoot stackheight is 18.86mm and heel is 22.67mm. There is no arch support at all and you can practically fold the shoe and put it in your pocket. It's also super light.
For a lower overall stack height, there's the Nike Kobe AD Mid 1. Forefoot: 16.57mm, rear: 21.80mm, offset: 5.23mm.
A cheaper, outdoor viable option is the Kyrie Flytrap 1. The offset on this one is greater, but the stackheight is super low: fore: 13.23mm, rear: 20.14mm, offset: 6.91. This is likely the lowest most un-cushioned but actual modern basketball shoe you can buy atm.
As a fair warning, I personally wouldn't wear any of the above shoes because I don't consider them supportive or cushioned enough (too many injuries I'm afraid). However all of them are professional-grade shoes and people swear by them.
As an additional note, if you want minimalism avoid Adidas because a ~10mm offset is a standard for their bball shoes (but on the other hand if you want supportive shoes, Adidas does tend to do a better job than Nike).
As for the shoe you bought, I think it has the disadvantage of being both too high and lacking upper support (the upper materials are too flimsy and there's no lateral support material to cage your foot onto the footbed). You could easy roll your ankle in that. The traction pattern will also be slippery on lateral movements, because the lines are all horizontal rather than multi-directional.
