Here's some free advice, since you asked:
1. The difference between those who "make it" and "are successful" is often determined by factors that are beyond your control. And if you want to get totally metaphysical about it, you (and only you) really get to decide what success is to you.
2. What you can control is how hard you work, how you treat others, how willing you are to be humble, how much you are willing to sacrifice in comfort and stability to find your right place and avocation.
3. What is important to you now may not be important to you in 10, 20, 30 years...and that's ok.
The good news is that, as someone who isn't even in your 20's yet, you have a wonderful opportunity to try a whole bunch of different things without any real consequences! Now is the time to play around and figure out what you like to do and what you don't like to do. Good on you for wanting to figure this out now and for honestly exploring your options.
In my 20's I worked in an industry that I was passionate about. It was (relatively) glamorous, I was around famous, successful people and it was fun. Being around the thing that I was MOST intrigued by day-in and day-out was fantastic. But there were many trade-offs - long hours that included lots of nights, weekends, holidays, etc; I was doing tasks that didn't require a lot of creative/independent thinking on my part; I was constantly around people that were self-involved, entitled, rude and vapid.
Most important for this discussion, it burned me out a bit on that thing that I love(d). I don't regret the experience and am grateful for what I learned and for the fun that I had. For me, I learned that I DIDN'T want to be in that particular line of work because the "work" sort of ruined the fun of that thing for me. YMMV with pinball.
So, you can totally jump into doing something pinball-related full-time as a career choice now if you want. You may find that you have an aptitude for it and we'll all say we knew you when.
Or...you can continue to work your well-paying job that has some time flexibility while you slowly build up a side business that is pinball-related. Then, if the pinball job becomes profitable, you can transition to that full-time and brag to all of us here about how great your life is!
Or...you can continue to hustle in your current line of work and build resources that allow you to enjoy pinball as a hobby without the threat of turning you against your passion. Then you can brag to everyone here about how great and vast your collection of pinball machines is and how successful you are in life.
Regardless, you have your whole life ahead of you.
