No, in fact you should assume that it will not work with smartthings. HomeKit and smartthings are two completely different platforms at this time.
There are a few devices that will work with both, but they will say so on the box. This includes some Phillips hue devices, some Meross models, Lutron Caseta with their SmartBridge, some Yale by August smart locks, some Arlo camera models, Ecobee thermostats, and a few others.
There is a list in the community – created wiki of devices that work with both listed by device class:

This may all change late next year once the new Matter standard is deployed, since both Apple HomeKit and smartthings have said they will offer some matter support. But we won’t know for sure what’s going to happen with that until devices are actually released to market.
