Yeah it’s about units. It is also however important to balance the game at most skill points.
For example if a strategy that is easy to implement and relatively strong emerges, then you will have very boring games at low level and the only way to get out of the low rank would be to learn to counter one specific strategy. (This is for example what happened in the beginning of SC1 with Zerg rush and SC2 and M&Ms)
