No, valencies are just the number of valence electrons, i.e. the number of electrons in outermost orbit.
Carbon bonds with methane by sharing electrons, thus forming a covalent bond. Valencies come into play only in ionic bonds, where atoms lose or gain electrons to achieve octet state (stability). But here, Carbon doesn't lose or gain electrons, basically carbon can't(to know more, refer NCERT class 10, chapter 4). And for these reasons, carbon shares electrons.
Carbon shares its four electrons with four electrons of hydrogen, and thus carbon completes 8 electron valence shell, while, the four hydrogen atoms complete their 2 electron valence shell.
Methane is CH₄

It is formed by one carbon atom and four hydrogen atoms . Hydrogen has its valency 1 and carbon being tetravalent needs four valence electrons to acquire noble gas configuration, where it shares its 4 electrons with four hydrogen atoms. Therefore, the valency of carbon atoms in methane is 4.
