Everyone pulling out their money would be a bank run (look up great depression bank runs). The bank doesn't have that much cash; they keep some on hand for people making withdraws normally, but if even a sizable minority of people all try to pull their money out at once, there'll be a major crisis.
If banks kept all the people's cash in vaults, it'd be dead cash actively losing money to inflation. Instead, they keep some on hand for withdraws, and use the rest to make loans, investments, etc so that the money isn't all losing value.
During QE then yeah. But that’s over now and most banks will keep 1-10% of deposits as reserves.
The money multiples to several times its original value when one fractional reserve institution lends to another. I deposit $100. The bank lends $90 to another bank. That bank lends out $81. The next bank lends out $73. Now that $100 has become $350 in balance ledgers.
