What could happen if I do not pay my rent or do not move within the 3 days?

The landlord must go to court to evict you.

After the 3 days are over, the landlord cannot simply put you out in the street, change the locks, or have the police or sheriff evict you without going to court first. The 3-Day notice is only the first step in the eviction process. The landlord must go to court and get a judge’s order to get the rent and the house or apartment back. For a short explanation of the eviction process, see PG. 398.
