No, you shouldn't expect that. When you register a trademark, you do it for a specific region (country, EU...) and for a particular purpose (industry). In principle you could try to trademark a name everywhere in the world for every purpose imaginable, but it would be very very hard since any owner of an existing trademark can object if they think there is a chance of your name causing confusion with theirs and the resolution process can take time and be ultimately unsuccessful for you. So nobody actually does that. Strength of a trademark really lies in both a) being registered and b) being actively used (first by you, but also by others). I think it is more useful to think of a domain as a digital equivalent of a sign hanged above the shop entrance. I think it affords you roughly the same level of protection. IANAL, but I have registered a trademark years ago and had at that time spent some effort in getting acquainted with laws. They may have changed since.
