Real Russian people are called "Rusichi/русичи" in Slavic, literally: "sons of Rus`". They are direct ascendants of citizens of town of Russia. Later, they are assimilated, so they forgot their language and culture. Major part of them are assimilated by Slavic tribes at territory of central and west Ukraine and Belarus`, so this territory got name "Russia" in 9 century. Slavic people of Russia/Русь are called "Rusyns/русины" (y as in lynx), literally: "they are Rus`", or "Russish/руські", literally: "belongs to Rus`". Name "Rusyns" was popular in Habsburg Monarchy, while name "Russish" was popular in Russian Empire. People of Russian Federation are called "Russish/руские", literally: "belongs to Rus`", or "Rossiiane/россияне", literaly: People of Russia/Россия, "Russish" means here believers of Russian Church, mostly Tatars, Erzan`, Mordva, and many other peoples, known as "Russificated peoples/обрусевшие народы". So, Ukrainians are not "real Russians". Real Russians are assimilated and now are called Ukrainians, Belorussians, Cossacks, Russians, Lithuanians, etc.
