This has to do with polarity vs. non polarity.
0-1.4 is NP
1.4-1.9 is P
What is the number for ionic bonds? is it greater than 1.7? If it is, then how come its not Polar?

Ionic is above the 1.9 you show for, polar covalent. The maximum EN difference is 3.3, the smallest is zero, so 1.7 is more or less the half way point.
The dividing lines between the 3 categories is not a sharp border. The higher the EN difference gets, the more pronounced the polarity.
Ionic compunds are very polar, which means having charges. In ionic compounds, the electrons are transferred, not merely shared.
We only differentiate polar / non-polar with the covalent bonds

The differnce between the electronegetivities of the atoms determines the degree of polarity and with that the type of bonding adopted. A difference of 2.0 or more is diffinative of ionic bonding. Values less than 0.4 a largely covalent and values in between a polar covalent
