Is pubkey collision possible in devnet?

[clouds56]

Problem

I build the latest commit of this repo 27eff84 on macOS 10.15.7 (x86_64, release), and generate an account using solana-keygen new -o /Users/***/.config/solana/id.json (around Jul 2, 2024, 08:23:29 UTC), the generated PubKey is AbKn6uqngf4ZZozDb2Bz6vjkrNt4o8BDHBbiiP34v5h6, when I import it to playground and found there's already 5 SOL in it, the transfer occurs yesterday, Jul 1, 2024 at 06:17:07 UTC.

Is this a collision? Is this possible?
