Wheels on skates do not have grooves because a smooth surface provides better contact with the ground, which enhances stability and allows for smoother gliding. Grooves could create uneven contact, leading to instability and reduced control. Additionally, the absence of grooves helps to minimize friction, enabling skaters to achieve higher speeds and perform tricks more effectively. Overall, a solid wheel design is essential for optimal performance in skating.
Its the wheels that are different. Outdoor wheels do not have the grooves, which means you don't feel as many bumps outdoors. Indoor wheels have grooves, which helps you run smoother. If you wore indoor wheels outdoors, you would feel every little bump and pebble. Plus, outdoor terrain with indoor wheels wrecks the wheels.
Small wheels have little rolling friction and helps to move faster in Skates
there are 4 wheels in an in-line skate
Another name for roller skates is "inline skates," particularly when referring to skates with wheels arranged in a single line. However, traditional roller skates, which have two pairs of wheels side by side, are commonly just referred to as "roller skates." Depending on the context, they may also be called "quad skates."

Some skates have smaller wheels. These are generally on artistic style skates. I believe the idea behind it is that they have less surface area on the floor to slide better when twirling and such to be more similar to ice skating styles. They are also less likely to collide with each other and lock up. If you don't think you like this kind, look into speed skates. They have the larger wheels and are popular right now.
I guess if you took off the blade and put on wheels you could but you cannot roller skate in ice skates
