Why is number 19 important in Islam?

Answer:

Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

The number you mentioned has no significance in Islam and anybody who claims so is a liar who talks about what he does not know. So, we warn the questioner from the person who mentioned this to him as he might be a juggler or from a bad deviated sect like the Batinya (secret, concealed sect).
Allah knows best
