Trouble with False Counts

Hey everyone! I'm currently learning the most basic false counts, and I'm running into some problems. Personally, I'm learning through YouTube videos before diving into buying a book, and DG2K Magic's channel has been super helpful (in case anyone's interested).

Like I said, I'm getting stuck on the false counts, specifically I'm learning them from this video: https://youtu.be/kRrG1vhdrQo?si=6Kf4KqM-uzVv4uPt

The first two techniques (loop count and push-off count) are giving me trouble when dealing two cards because they come unsquared very easily as I pull them with my thumb. I'm not sure if I should "fake" the drag to keep them squared, improve my right-hand technique for picking them up, or switch to a less slippery deck...

Any help would be greatly appreciated, and if anyone has any tips on something the video doesn't explain, or a link to another related video, that would be awesome. Thanks so much!!
