It's definitely worth trying if you're interested.

I would not recommend buying a console or gaming PC first as that is a money sink that you're not sure is worth it yet. My gaming PC broke when I arrived at university, and I got by playing less graphically intensive games on my standard laptop for a few years.

Good games I'd recommend to start with:

• Stardew Valley — cosy, charming farming game that you can play at your own pace. Has great characters that you get to know, and fun, simple, rewarding gameplay. My girlfriend got really into this game.
• Minecraft — this is where many of us started as kids. It's an excellent game that's fun for all ages. There isn't a clear goal so it's more about making your own fun.
• Vampire Survivors — extremely fun, simple, cheap, and addicting game. Play at your own risk.
• LIMBO — a puzzle game classic with a unique, dark aesthetic. Only takes a couple of hours to complete.
• INSIDE — made by the same people as Limbo. Grabbed me and wouldn't let go for the whole 4 hour experience. I don't play many puzzle games but I couldn't get enough of this one. Probably because of the narrative.

Those can all be played on the average laptop or desktop anyone would have.

Best of luck on your journey! Feel free to reply with any questions or suggestions for specific genres and such. My girlfriend didn't play video games until I introduced them to her, and the most important thing was that I didn't try to force any games on her, just show her what there was and let her interest lead the way. So take a look at all the suggestions people are leaving and go with what interests you most. And if you're not enjoying a game, it's okay to go play a different one.

(Also, Steam provides free, no-questions-asked refunds for any games purchased that both 1) were bought less than 2 weeks ago, and 2) have less than 2 hours of game time. So you can always demo a game to see if you like it and return it easily if not.)
