(DEPENDS is for build time dependencies and you add the recipe providing
the sources for it, RDEPENDS_${PN} is for runtime dependencies and you
add packages to it (it is common to have the same name for the recipe and
the main package built by it)).

I can suggest watching/listening to Live Coding sessions done by Josef
available on Yocto project's Youtube channel:
https://www.youtube.com/playlist?list=PLD4M5FoHz-TxMfBFrDKfIS_GLY25Qsfyj
It should help you get started and understand the basics.
Kind regards,
Quentin
