Little Endian in Instruction

I'm learning about RISC-V instructions in Computer Architecture. What i wonder is, because of little endian, any number in RISC-V's instruction's little digit is on little bit. I know that RISC-V use little endian to express data in memory. but I'm not sure it is same to express number in instructions.

for example, add instruction has that form, [funct7][rs2][rs1][funct3][rd][opcode], MSB is in funct7, LSB is in opcode. and rs1, rs2, rd is some number with 5bits. if [rd] is 0b00001, position of 1 is LSB in rd's 5 bits. this point is my question. is reason that 1's position is LSB, RISC-V use little endian? if that is right, is (0b00001's) position of 1, MSB in big endian?
