1) The values may vary depending on the sensor manufacturer and the intended application.

2) The temperature coefficient of the NTC is extremely temperature-dependent, the values given are only orientation values!

3) Other variants of this type also exist, which differ in the characteristic values!

This informative diagram shows that an extremely wide resistance range is covered, especially with NTC sensors:
