Your confusion is exactly what I’m talking about.

There are two steps when removing the president:

1. Congress can vote to impeach, with simple majority
2. Senate holds an impeachment trial. They need 2/3s vote to find the president guilty of the charges (convict the president).

What everyone gets confused by is that twice congress found enough evidence to open a trial to remove Trump, but he was never convicted by the Senate/found guilty.
