Which controller is used in industries nowadays?

The Microchip PIC trademark is usually associated with 8-bit processors, especially the PIC16 series, but there are also 16-bit and 32-bit PIC microcontrollers. The complete line includes PIC10, 12, 16 and 18, all 8-bit; PIC24 and dsPIC (with DSP), 16-bit; and PIC32M, 32-bit which run the MIPS RISC instruction set. But sales of 8-bit PICs are much larger than the larger PIC devices.
ARM7 is a relatively old ARM core family, perhaps the OP meant ARM Cortex M7, which are microcontrollers similar to the 32-bit PICs. Since 2016, when Microchip bought Atmel, it has offered both MIPS and ARM-based 32-bit MCUs. ARM Cortex processors are made by several other companies in addition to Microchip.
When Microchip bought Atmel, they also picked up all of its 8-bit AVR markets also, which was substantial. They are used in the Arduino platform, for example.
If we were to restrict ourselves to just the 8-bit PICs plus 8-bit AVRs, it would still be difficult to compare them with the ARM Cortex M7 sales, since several companies make them.
However, we can compare all 8-bit microcontrollers with all 32-bit microcontrollers, which may be what the OP was really driving at. And here we see that for 2017, the market share was about the same, with the 8-bitters still slightly ahead.

Note this was a forecast done in 2014, so the numbers may be off some. But the trend is clear; while the 16-bitters are not growing, the 8 and 32-bit are still neck and neck. And this is dollar figures; since the 8-bitters costs substantially less, their actual numbers still far exceed the 32-bit devices. And Microchip is the leading producer of 8-bit microcontrollers (PIC+AVR).
So I would venture that comparing PICs to ARM Cortex M7s, the PICs are still ahead.
PIC is a microcontroller. The ARM is a core. ARM cores are used both in microcontrollers (MCU) and microprocessors(MPU). The two are not comparable.
Both are used in the industry. PIC is used for applications that do not demand high processing capabilities and speed. ARM-based MPU or MCU are used for an application requiring a significant amount of speed and power. The choice is entirely application dependent.
BTW, the industry is huge. Very very huge. It stretches from India to the USA and then back to India. It stretches from India to the Arctic, all the way South to Antarctica and then back again to India. Don’t you think just two choices are a bit insignificant quantity? There are thousands of flavors of controllers available:
