Yes. Looking at https://www.engineeringtoolbox.com/standard-atmosphere-d_604.html https://www.engineeringtoolbox.com/standard-atmosphere-d_604..., the atmosphere is about 9% as dense at 60,000ft compared to sea level. While you get some drag advantages, you're going to have serious trouble with both lift and thrust using conventional "low-cost drone" tech up there.
Quadrotors are right out for a number of reasons, but a purpose-built fixed wing might be possible although likely not for under $1000. You'll need massive wings and some kind of propulsion system (likely hydrocarbon-based) that can suck in a huge amount of the thin atmosphere to try to get what little oxygen is available. The prevailing winds at altitude can be moving quite fast, so you'll need an airframe that can handle those forces as well as a propulsion system that can generate enough thrust to overcome those headwinds.
