It depends on their format. A lot of competitive games have abilities and different loadout options that allow you to try different playstyles on purpose and practice getting better with them, while the battle royale's format forces you to deal with what you find, preventing practice with specific setups.
For example MOBAs allow you to pick heroes who play very very differently and allow you to become proficient in a number of different playstyles purposefully on your own time, so you feel the progression more directly and if you dead end with one character you can try more.
