• こう云う (more typically written こう言う) means "such, this sort of"
• 慣れる means "to get used to, to grow accustomed to"

Kanji

Kanji	N-level	Occurs in how many common words?
元	N4	36 (including the very common 元気, げんき as in the typical greeting 元気ですか).
慣	N3	10

Grammar

慣れ切る combines the stem of 慣れる, "to get used to" with 切る, which on its own means "to cut." This stem + 切る construction means "to do to completion, to X completely/fully." In this case, 慣れ切る translations to "to get fully used to," that is "to be used to, to be familiar with."

Translation

Because he was a thief from the beginning, he was completely used to such a thing since long ago.
