Despite the myriad of images of destroyed tanks there is no proof as yet as to what actually blew them up.
One video of a tank being blown does not show or prove anything more than that, nor does it show what happened before or after, failed attempts, surrounding forces, etc. Whatever the video shows, ask what you do not see.

“there is no proof as yet as to what actually blew them up.”
The Ukrainians have their internal reporting, but the credibility of what they might report externally is naturally in doubt during war.
The indications that I have heard is that there has been quite a mix of causes for Russian tank losses - Yes, guided missiles like Javelin and NLAWs, as well as other direct fire Infantry weapons like RPGs; but also artillery, drone attacks, aviation, mines, tank on tank engagements, and a large number just abandoned or broken down/out of fuel.
