Hey, you clearly know the more clinical and statistical side of things, but, you should book a GP appointment (it isn't a waste of their time) and speak about this with them. You might also want to try calling the Mind Infoline for some general information on this. Basically, the answer is 'maybe', Schizophrenia has a natural incidence of about 1% and in identical twin studies it is 50%, so there is a strong genetic component, however, that doesn't mean you will develop it.
I would advise not to do any drugs and even moderate your alcohol as some research shows that can set off FEP too which then could develop into schizophrenia.
Most importantly, i know psychosis has a lot of stigma and it is a really scary thing, but the treatment options that are now available are pretty great, even those with treatment resistant schizophrenia can find peace and a suitable treatment plan. You can be very successful and very happy with schizophrenia, I have Polymorphic Psychotic Disorder w/h Symptoms of Schizophrenia (basically randomly intermittent periods of paranoid psychosis) and this means I will most likely develop full on schizophrenia at some point in my life. I have also been hospitalized on a few occasions and received community treatment in other cases. But all that being said, I am a really successful person and I am about to become a barrister (hence why this is an anonymous reply), you can too. It is scary, but it isn't like it used to be and you can do so much even with these scary acute mental health difficulties.
My advice, outside of speaking to a GP, is actually to get involved in some psychosis support groups, google 'Epic Minds' or even reach out on some groups online.
