Roulette Wheel Layout
The roulette wheel is not arranged like the betting table. Wheel order spreads colors, high and low numbers, and odd and even numbers around the rim.
Quick answer
European roulette uses 37 pockets: 0 and 1-36. American roulette uses 38 pockets: 0, 00, and 1-36. The added double zero is why American roulette has a higher house edge.

Wheel layout vs table layout
The table is for placement
The table groups numbers into rows, dozens, columns, colors, and outside bet areas so players can place chips clearly.
The wheel is for resolution
The ball lands on the wheel. The wheel order distributes neighboring pockets, but it does not make any number due after prior spins.
