Your assumption could just be true as well. At this point, we can

According to some probabilities we should have been visited already in
the past, but maybe there were no humans on earth at that time. Also,
the visitors might not want us to know they were here. Which is not to
say that we will not be visited again in the future, but maybe we will
be extinct by that time. We are dealing with huge amounts of space-time
- humans have been on earth only a very short time.
So, maybe the visitors are so advanced that we don't know they are
already here. Or, it could be that if aliens detected humans on earth we
might be perceived as a species of parasite and they would want to
exterminate us. Or, we would want to exterminate them - look what
happened to the Neanderthals.
It's very difficult to imagine a benign intelligence out there, seeing
as how humans are trying to kill each other on earth today - Sunni
versus Shiite. The only historical record of benign humans on earth were
the ancient Buddhists in Tibet, which was a long time ago and will
probably never be repeated. Go figure.

planets in the galaxy that are habitable and one percent of these
have alien humanoids, then there will be one billion exoplanets
that have humanoids in them.

Similarly, if you take one billionth of the one billion, then
there will be at least one exoplanet with alien humanoids in it.
So, the chances are good that the true answer lies in between
one and a billion.
