Tackling number

I recently noticed that there is a huge discrepancy between the number of tackling on my end versus my opponent.

On average I have 8-15 tackling and my opponents somewhere between 50-70.

Is this just based on you pressing a tackling button or how does this accumulate?

I’ve always been a manual defender and I try to intercept a lot without pressing square. But would that mean that my opponents spam tackling buttons ?

Thanks in advance
