The statement is true.
A crime is an act committed by a person who goes against the laws of a country or region. Who executes this act is called criminal.
The basic idea of what is called "crimes" is that they are thought to be things that can cause problems for another person. Things like killing another person, hurting another person or stealing someone else are crimes in most countries. In addition, it can be a crime to have or sell contraband of weapons or illegal drugs.
