Don't you need to reach $100 to get your first Adsense payment? That's what it says in ToS and also I remember getting my first check for like $106 a few years back.
AdSense is not easy and quick money… First of all establish your site – it takes years… Fresh content + SEO on a regular basis… And after all that place AdSense code on site… And $50 can be your daily average.
