best resources for a)free

1. Bitcoin Stackexchange
2. Reddit: r/bitcoin, r/BitcoinBeginners/, r/lightningnetwork/
3. Bitcointalk
4. GitHub repositories for different Bitcoin projects
5. IRC channels
6. Bitcoin dev mailing list: How can I efficiently search the bitcoin-dev mailing list for discussion of a specific term?

Try things, read more about them and ask questions. If starting from scratch first thing you can do is try running and using a Bitcoin full node. Use testnet or regtest for experiments.

You can download Bitcoin Core or Bitcoin Knots for full node.
