It takes 2 1/2 hrs to reach the 3,800 metre depth where the Titanic lies.
Comms were lost 1 hour 45 mins into the dive.
So the sub would have been around 2,700 metre depth. Very close to that 3,000 metre maximum depth rating!
The fact that the 2021 and 2022 (one in each year) Titan expeditions went well seems to be just dumb luck.
The last expedition to the wreck of the Titanic with a sub that had the proper depth rating was in 2019 (a sub called Limiting Factor - which is rated at 11km! depth).
The Mir submersibles used by James Cameron 33 times had a rating of 6km.
There were never new subs built by OceanGate, it appears to have tried to patch up the original Titan and make do with that.

Suggests maybe they were running out of money and decided to take their chances.
If they were only running one mission a year, that's definitely not enough to convince me. That's "we're still in the experimental phase" shit.
