That's not true. If you have offspring, they have some of your genes. They don't have to be fertile.

For a better example, take humans: If you have a child and they grow up to be infertile, you have still passed on your genes. If they choose not to have children - even if fertile - you've still passed on your genes. Your particular mix of genes just won't live on in subsequent generations. Grandchildren aren't a requirement for you to simply pass on genes.

I think we all know they're talking on an evolutionary level here, not just individuals...

You shouldn't "Uh, no" people if you're just 50% correct some of the time.

The “Uh no” was to someone who tried to correct someone who was right while being 100% wrong themselves. And in the context, I was 100% right.

If your children are infertile, you are from an evolutionary perspective a dead end.
