More specifically, because of the gyroscopic motion of the rotating wheel

I’m curious is because I saw something recently that said the gyroscopic motion is only like 30% of what keeps a bike upright and that the forward motion is a more important factor.

I have seen videos of bikes on treadmills because YouTube algorithm, and they just need something to keep the handlebars straight and something to keep the bike in place as the treadmill speeds up and slows down. nothing is needed to keep it from falling over at that point

Bikes are stabilized by several things that all help. Gyroscopic forces aren't necessary, but they help slow how fast it falls. Ultimately, when they start to tilt, you steer to move the center of mass back in the other direction. That would still work on a treadmill because turning the front wheel will still move it laterally on the treadmill. There's stuff you can do with the frame design so that part of that steering happens automatically, but you can also do it manually (it is possible to ride a bike with counter-rotating wheels to cancel gyroscopic forces and the frame trail purposefully designed to amplify tilting instead of resisting. You just have to actively steer it) Unicycles are similar but with more direct steering control. You can move center of mass forward/backwards with the pedals, and side to side by leaning or pivoting and pedaling. It's like doing a track stand on a bike with slightly different controls

Roller trainers have been a thing for a long time. https://www.youtube.com/watch?v=d1SOJBSjmn4 There is definitely a degree of difficulty to them, and the fails seem to be very sudden. A lot of people start on them in a hallway so they can touch a wall to regain balance as needed. On an actual running treadmill though, yeah having something to keep you in place front to back must be key, that seems like it has the potential to end painfully with a treadmill belt sanding down your face while you try to get untangled from the bike.

Oh yeah bikes. It's because the axis of the front wheel is positioned very slightly forward of the axis of steering, which makes it unstable. A slight wobble will cause the wheel to turn AWAY in a way that self-corrects (if you are moving). This effect doesn't happen on a treadmill, or if you don't have this offset, and a bike with a reversed front fork is surprisingly hard to turn and balance - it will try to behave like a trolley wheel and seek to follow the current motion.
