Why do I only needis 50+ so confirmation only needed instead of n/2 + 1 confirmation where n is the number of node in the network?

Why do I only need 50+ so confirmation instead of n/2 + 1 confirmation where n is the number of node in the network?

In a typical consensus algorithm like raft, it requires majority of node to agree on something, but I find ethereeum transactions to only need about 50 confirmations for a transaction to be approved in coinbase.

Is this an engineering approximation such that if there is 50+ confirmation the probability of transaction to stick is very high, or am I understanding the theory wrong?
