I mean, this is a bit subtle. With a fixed front fork, it's very difficult to get a bike to lean. It's just the case that with a free front fork, shifting balance may be enough to get the wheel to counter steer, which can initiate a deeper lean. Having said that, it's 100% the case that a 2 wheeled bike with rounded tires in a lean will turn. Just consider that the circumference of the tire shortens as you approach the edge, it must travel a shorter distance per revolution. so without sliding, it clearly needs to turn. In-fact, at speed, the lean of a bike is the primary factor that contributes to the turn.

It isn't difficult at all, it is just a matter of hanging to the side of the bike while pushing it to the other side. Rounded tyres do not make the bike turn either since both of them lean at the same angle and thus have a similar effective circumference. The same happens when you cycle with a strong side wind, you'll lean towards the wind to keep the bike from being blown over. The way you enter the leaning position is different though since you're not leaning away from the bike, instead you (unconsciously) make a slight turn towards the wind to get the bike to lean.
