Yes, but that doesn’t mean that these individuals do not have a valid case... it just means the issue was much too hot for any court to touch and they used the “lack of standing” criteria as an excuse to refuse to hear them.
As it has turned out, probably 90% of the US citizens have indeed suffered individual harm from our current President and therefore would have had “standing” to present a case.
He was not eligible then and never will be.
Keep in mind, too, that the likelihood of getting a court to rule *any* candidate or politician ineligible is about nil, no matter how obvious the issue may be, because doing so would potentially invalidate everything Obama has done. Even a court which was not an Obama or Clinton appointee wouldn’t do so simply on the basis of how much upheaval it would create.
