I Corinthians 12:1-3: The practice of speaking in tongues was not a new occurrence. The Corinthians had spoken in tongues as part of the worship of idols and some had cursed Christ in tongues with an interpreter.
I Corinthians 12:4-11: The Holy Spirit indeed gifted certain individuals with the gift of tongues. It was one of a multitude of gifts.
I Corinthians 12:14-18: Miraculous and revelatory gifts were given at God's discretion to whom He willed (I Corinthians 12:27-30).
Not everyone spoke in tongues. Everyone did not have that gift.
