Does the island of stability really exist ?

Some rumors are about this. I think it is wishful thinking. There is no proof of 'stable' isotopes (i.e. half lives more than even a day) of the 100+ elements, except one Dubnium isotope (28 hours). And all 110+ elements even in a fraction of a second.

Completely useless so I guess mankind will never get knowledge of chemical or physical properties of these (actually virtual) elements, unless one makes one of these elements with far less neutrons or no neutrons at all ???

It probably is a thing. But stability is a relative term.
I think it is probably more like a coral reef in deep water than an actual island. That is, more stable than surrounding isotopes but nothing of any practical use.

(Statement based on intuition only without any supporting evidence. But then, I don't think anyone has evidence so I am not alone in speculating.)

The coral reef analogy is very good.
The most stable isotopes in the 110-116 region have half-lives less than 2 minutes.
But we have not succeeded in making the hypothetical 'more stable' isotopes with higher neutron counts.

I do not think that there any more absolutely stable isotopes: Any such would presumably have been formed in neutron star collisions, and none seem to be around anymore, so I figure the longest half-lives would not exceed perhaps a few hundred million years.
