How can we say space is seperable?
Yes trivial topology is seperable. We can say a topological space is seperable if and only if there exists at least one countable dense subset of $X$
If we consider singletons,
$\overline {\{x\}} = X$ and we know that singletons are countable thus trivial topology is seperable.
Besides any non-empty subset of $X$ is dense too
Any non-empty subset of $X$ is dense.
