Is it difficult to get an FSJ position in Germany?

I’m 23 years old and I have a degree in IT, but I don’t really see myself working in this field. I would like to do one year, or possibly 18 months, of volunteering in a hospital, nursing home, or something else where I can work directly with people. I just don’t want to have an office job anymore. I’m also very interested in doing an Ausbildung in Germany. Do you think it would be possible to do an FSJ first and then start an Ausbildung in nursing?

A little about me: I’m Brazilian, I have €10,000 in savings, and I speak English at B2 level and German at B2 level. Do you think this would be a realistic path?
