Learn: Task vs Thread
A Thread is an operating system thread: expensive to create, and it holds memory the whole time.
A Task is a promise of a result. CPU work started with Task.Run runs on a shared pool of threads. A task waiting for I/O (a web call, a database) holds no thread at all while it waits.
In modern C#, use Task and async/await; create a Thread yourself only for rare long-running, dedicated work.
