Genetic liability is important, but it does not determine everything. Some people are just more vulnerable to psychotic experiences, because they are more likely to perceive things from their environment. Other things from the environment can also play a role. Some drugs such as cannabis can also make you more liable to psychotic symptoms. Finally, there are some circumstances that can lead to more chance of psychotic symptoms, for example, being under stress for a long time. And negative experiences in your early youth, for example, sexual abuse can also increase the chances for psychosis.

It is the sum of many things that may cause psychosis, your liability, your circumstances, things that happen in your life, et cetera, et cetera.
