In the statitics of each beyblade, more explosion means the beyblade is more easy to explode himself or means he can explode others more easily?

Burst. The word you're looking for is Burst.

The statistics that come on the packages of Hasbro and TT Beyblades are meaningless: you cannot accurately capture the strengths and weaknesses of a given part in a given combo against another combo with a single number.

The "Burst" statistic means how likely it is to burst the opposing bey, supposedly. And as before, it is meaningless.
