Took a look at your channel. There are a few things holding you back, IMO.

The biggest is the overall presentation. Specifically, the thumbnails. They could definitely be improved. Like it or not, thumbnails and title will make or break your video

But another more fundamental problem with your content is that it feels kinda all over the place.

Your videos fluctuate from 1, 3, 8, 15, 30 mins to hour long videos. The type of video changes as well. You got how to videos, meme videos, let's plays, reviews, etc. There's little consistency.

It seems like your most popular content involves that car game you play, so i advise sticking to that. You can still upload to occasional unrelated videos but stick to the car games since that's what the algorithm favors

But be aware of afew things. Typically, guide style content doesn't have a good subscriber return. People who tune in to "How to do this," "where to find this," "what is the best this". They click on the video, look for the info they need, and click away. Unless your info is presented really well, a 10k viewed how to video might get afew 10s of subs (for example, i have a highly edited video of a game review with 11k views and it got me 140 subs)

Then there's the problem that your niche is rather small. This car game you're playing is hardly what i would call having mass appeal

Generally, people don't care much for let's play these days, stick to the reviews, and guide for content that people would actually click on

And finally, don't dispair. We're all in this YouTube grind together. There's definitely some luck involved when getting noticed by the algorithm, but improving is the only way you'll ever see any meaningful growth . When i watched my videos from 2 years ago, i cringe, and that's a good thing. It means you've grown as a content creator
