Sure, but Fortnite's UI is set up to sell to you the whole time. After every match you can see unlocks. Before every match you spend time surrounded by other players with their skins and emotes.

The relationship between EXP and levels in each season only really reward you if you have a battle pass - so the more you play the more the pass seems like an attractive purchase. Once you have the pass, you're then encouraged to play more than you might otherwise want to in order to max out the time-limited rewards.
