Does Ethereum 2.0 support 100K TPS per shard or totally?

Hello recently i read that Ethereum 2.0 will handle 100K. Basically, this shift to proof-of-stake and increased scalability is aimed at making Ethereum more decentralized. Currently, the Ethereum blockchain processes transactions at around 12-15 TPS (transactions per second). The new ETH 2.0 proof-of-stake system is expected to scale this up to around 100,000 TPS. That’s a huge jump that could make Ethereum the ultimate go-to chain for dApp developers and other DeFi protocols.

My question now is 100k TPS is an estimation for a total of 64 shards that will be supported or 100K TPS per shard. The second one seems a bit unreasonable am i correct?
