how can Homo sapiens and Neanderthal be different species but Neanderthal dna is common in modern day people

To my 5 year old knowledge I thought Neanderthals were different species but for us to have part of their dna that means they got jiggy together and created fertile off spring with Homo sapiens but when a donkey and a horse do it they make infertile offspring? Are we not like actual separate species?

If two species are close enough together in an evolutionary sense they are sometimes able to breed. Think dogs and wolves or lions and tigers. We basically absorbed Neanderthals and cause their extinction by breeding with them
