比如说某个基因造成某种疾病是科学，而有家族史的疾病可能使其后代有患病的可能就不是科学，只是一个统计结果。

这个是不正确的定义，被验证过的“基因造成某种疾病“是事实，是真理，你这个是把真理和科学等同了，这个是不对的。真理只不过是科学的一部分，一些错误的认识也可以是科学。

科学的定义有5条，（基于https://www.merriam-webster.com/dictionary/science）

1 : the state of knowing : knowledge as distinguished from ignorance or misunderstanding
2a : a department of systematized knowledge as an object of study
// the science of theology
b : something (such as a sport or technique) that may be studied or learned like systematized knowledge
// have it down to a science
3a : knowledge or a system of knowledge covering general truths or the operation of general laws especially as obtained and tested through scientific method
b : such knowledge or such a system of knowledge concerned with the physical world and its phenomena : NATURAL SCIENCE
4 : a system or method reconciling practical ends with scientific laws
// cooking is both a science and an art

家族史的疾病可能使其后代有患病的可能就不是科学，只是一个统计结果。

根据上面2（b）的定义，是科学
