It's just a matter of habit. At first it feels weird looking at the monitor and drawing somewhere else, but usually your brain gets used to it after a couple weeks of regular practice. I'd suggest just starting with simple things - lines, circles, hatching. Don't worry about complex drawings, just mess around with the tablet, feel the pen pressure, the speed. Get yourself Clip Studio Paint or Photoshop, or even free Krita will do just fine. The main thing is don't give up after the first day.
As for tutorials, look up YouTube channels like Sintaksis, Khudozhnik Online, or Linda. But I'd recommend watching not general tutorials about graphics tablets, but actual drawing lessons - composition basics, construction, anatomy. A tablet is just a tool, like a brush. If you already drew well with a pencil, then you've got the foundation, you just need to transfer it to digital. Draw from life a lot, copy works by artists you like - that's better than any tutorials.
One more tip: don't get hung up on perfect tablet and software settings. A lot of beginners spend months tweaking pen pressure and sensitivity instead of just drawing. Your Wacom One is already a good tablet, standard settings will work fine. Just draw at least half an hour a day - you'll notice huge progress in a month.
