Just to clarify, your channel is named Aces High Shorts, but I don't know if you intended that literally.
Most of those videos won't be classified as "shorts" by Youtube and not recommended on the Shorts browsing recommendation system.
That is not fully defined just by it's length but more importantly by it's aspect ratio.
"Landscape formats (wider than tall, e.g., 16:9) – not eligible. If wider than tall, it won't be classified as a Short; instead, it'll be uploaded as a standard YouTube video, even if it's under 60 seconds"
I assume you truly wanted Shorts if your purpose was advertising because true Shorts will receive vastly more impressions than standard vids. That's why their metrics are counted different.
I don't know what you are using but I recommend Davinci Resolve. They have a free version.

[Edit] If you want feedback I will add this. Shorts have harsher user behavior than standard vids because they are almost always watched on a phone and it is so easy to just swipe to the next vid if the current one isn't lighting you up.
Statistically most users will decide in the first 3-5 sec of a Short if they want to just swipe past.
I'd make the first 10 sec pure "money shot" with your best most dramatic visual cut or hook them with curiosity, fear, outrage, greed, or lust Like "Want to learn how to dominate the skies in the 109 like golden warrior God? I'm going to show you in this vid just how to do that and your enemies will hate you." Maybe not that obvious, but you get the picture. Set the hook. You have 3-5 seconds. Then introduce yourself and explain the lesson and the channel and the game etc. If you can convince them to hold off that swipe for 10 seconds, they are invested now and will probably finish the vid. Getting them to finish a vid super charges your algo ranking.
On the other hand, if your 3-5 sec doesn't hook they swipe off, that greatly damages your ranking in the algo and it will stop recommending your video because you made them look like they made a bad recommendation. They are taking a risk on you with they suggest your vid if the user hates it, it makes the algo look bad and Youtube will ghost you.

[Edit] A hint, look at your channel landing page. Notice you have Videos and a Playlist tabs, but no Shorts tab. I take that to mean none of your videos got classified as shorts.
