No, not really, you can start staking with as many as you want, see pooled staking: ethereum.org/en/staking/pools/

Staking pools are a collaborative approach to allow many with smaller amounts of ETH to obtain the 32 ETH required to activate a set of validator keys

You earn rewards proportional to the amount you stake

You only need 32 ETH to stake if you want to solo stake / home stake and you don’t pool resources with anyone else, see ethereum.org/en/staking/solo/
