No, Battlefield 6 is only available on EA Play Pro at launch. It might come to the standard EA Play subscription after about a year.
Can you tell me where you got this information from? I've been looking for a while, but the only thing I found was a quote on the game page saying we would receive a package, nothing about access.
You can possibly use the link below to confirm, but in essence, EA Play Pro gets "Day 1 access to full, premium editions of select new games, packed with added content and extras" whereas the regular version doesn't offer this as standard.

There's also the BF6 pre-order page itself, which only lists EA Play Pro.
