You should start with the computer to be honest, and start training/experimenting left and right, on a cheap one and get used to linux. Linux for smartphones isn't there yet, while it's pretty close as you can see in the vids above A second hand crappy computer/laptop is perfect to start with linux, to get used to the command line (which is awesome btw, once you're used to it, it's just some programs to know and basic protocols/commands to get started). And for that, a debian is a good start. It's not fancy it's just standard shit, the base of ubuntu btw and kali linux to just name those. As Terry A. Davis stated, Windows and macos are the equivalent of a car, while linux is the equivalent of a six wheeler... Expect some frustating moments, don't expect it to be just perfect and hassle free because that's not what it's going to be. Just like with a six wheeler... I'm full linux btw since almost 15 years now, and I'm not going back to macos or windows, ever. And I'm not living in hassle free world, and a lot of programs I use such as gimp to name just this one, have better, and even much better equivalents in the proprietary world, such as photoshop, and again, at the same time I don't regret anything It's not the best gun in minecraft, but it's still a gun and it's mine and I know it, I'm used to it. Everything is hard, choose your hard. The devil you know, etc...
