In the New Testament the Greek word for worship is προσκυνέω. It is a verb. Various forms of the word are used 68 times in the NT. From HELPS-Word Studies it means the following:
4352 proskynéō (from 4314 /prós, "towards" and kyneo, "to kiss") properly, to kiss the ground when prostrating before a superior; to worship, ready "to fall down/prostrate oneself to adore on one's knees" (DNTT); to "do obeisance" (BAGD).; suggests the willingness to make all necessary physical gestures of obeisance.]
Based on this from the greek and the examples we have in the NT....catholics are worshipping Mary.
The problem is with your line of reasoning here that the word for “worship” used in Scripture is not always applied to God. Among numerous Old Testament passages that can be provided to demonstrate “worship” of created beings (that was not forbidden), there is also Rev 3:9 which uses the exact same word (”proskyneo”) that you claim is only appropriately applied to God. It’s not given to God in that verse and in fact God Himself (Jesus) sanctions the “worship” of created beings in that verse.
