Draw on phone

How can you draw well on the phone? I've seen videos of people who draw on their cell phones and they do it super well, but when I do it it's so difficult for me and it's not even that I draw with my finger, but rather with a graphics tablet, but even so it's very difficult for me and it's the only option I have since my computer died a long time ago.

Does it happen to you? I feel like I can't adapt so the phrase that says "It's not the brush, it's the artist" or "A true artist does not depend on his tools" 😭😭
