While you'll find many choices of bed sheet fabric, cotton and cotton/poly blends are the most popular by far. But although blends are better at resisting wrinkles __ and are durable and inexpensive __ nothing beats the comfort and breathability of 100% cotton sheets.
However, those very high numbers can be deceptive. Most weavers consider 500 to 600 threads per inch to be the maximum count _ but extra threads (called picks) can be twisted into the weft, adding to the thread count without actually doing anything to make the fabric softer or more luxurious.
