Well, I guess the first step would be getting a decent computer (newer CPU is a must for sound processing), and then finding a DAW (digital audio interface) that interests you the most. And there are a lot out there.

I'm using Ableton in that video, though I also use Propellerhead Reason and Melodyne. There is also FL Studio, Logic, Cubase, Acid, Cakewalk, ProTools.. Lots out there.

So once you have the DAW you like or are interested in after doing some research, I would commit time to learning it. It's like, you want to learn to paint beautiful paintings? You have to first learn how to hold a brush.
Then you start to learn arrangement over time, building your songs, then maybe start getting into synthesizer design more in depth (and there are hundreds of synth programs out there), start learning about effects and automation, resampling and micro editing, then you start learning about balancing your song through mixing, equalization, compression, mastering..

It's a very very long road since a producer pretty much does everything from start to finish nowadays, but if that's something you want to do, there is a ton of support everywhere on the internet. I've been at it for the past 7 years now and am committed to making it my life. Others just do it as a hobby. Either way, I highly recommend checking it out.

I played drums for most of my life and that gives you a certain satisfaction, having an extremely emotional and almost primal connection with an instrument where so many of your thoughts and motions are effortless, maybe subconscious, certain complexities that an outsider who doesn't play what you play just can't wrap their heads around, because they don't know what the thought process and muscle memory feels like. Another drummer will always know, at least to some extent. Same goes for any other instrument, or artistic craft for that matter.
Being a producer gives you a whole different level of satisfaction.. Something where you create every single aspect of the music you're listening to, like you're a whole band, and the studio. Having complete control on that level is really something else.. Hard to explain. Very rewarding, but it takes a long time to make anything you feel proud of because it's a lot to learn, with a lot of areas to be able to grow in.
