Autorun doesn't exist anymore.
As long as you don't open any executables, you'll be fine.
What's the chance that the seller has a 0day (which would be veeery valuable) and is using it to steal data from someone random? Not worth it for sure on their side.
While autorun doesn't exist anymore, there's many many other methods of attack via usb.
Here's a list with 10 seconds of searching:

It's entirely possible this drive was made maliciously to pass on data from whatever unsuspecting soul uses it. The seller op bought from could even be a victim themselves. You just never know.
We're talking about an sd card here. The absolute majority of these attacks only work with USB drives.
And the rest either don't make sense or make use of a 0day, which, as I've already said, is inconceivable
How do you read a SD card? I usually put it in my SD card reader which is USB.
The SD card is still speaking SD protocol, the card reader bridges between USB and SD.
This only works with USB sticks because they're plugged on directly over USB and you don't know whether it'll present itself as a storage device or as a keyboard that immediately starts typing stuff and running a bunch of commands.
The risk is not the flash storage part, it's the USB interface.
But I don't think OP is saying the package came with an sd card reader as well that they used
Best security practices are pointless if you disregard them because they're inconvenient and unlikely to be necessary. Most needles I find on the ground are clean too, but I'm not just gonna stick them in me because the odds are in my favor.
Might as well get rid of your internet connection then.
And your shoes while you’re at it. Good luck walking on all those pinecones!
