Can I get all the rewards with the free pass and at the end buy the premium and get the premium rewards immediately or do I need to buy the pass first to start winning the premium rewards?

I've got 950 VP and sent this beautiful and I think almost photo-realistic image of Skye to the valorant support team in hopes I can get a cheeky 50VP to get the battlepass. ​ ​ https://preview.redd.it/lrtvhei5qoa71.png?wid...

Ik it's a dumb question but i'm here to make sure. Btw its for easy bots, so i can do it slow and steady so i can learn consistency and speed. Do you think music can influence that training process?
